Why You Still Think Like a Poor Person (Even If You Earn More)

You got the promotion. The salary jumped. For the first week, maybe two, something loosened in your chest. You could breathe. Then — almost without noticing — the old tightness crept back. You’re earning twice what you made five years ago, but you’re still checking your bank balance with one eye closed. Still flinching at restaurant bills. Still telling yourself you’ll start investing “when things settle down.” If that pattern sounds familiar, the issue isn’t your financial literacy — it’s the operating system underneath it. Your income upgraded. Your scarcity mindset didn’t.

This isn’t about gratitude or perspective. It’s about the psychological machinery that keeps running long after the circumstances that built it have disappeared. And until you see it clearly, no raise will ever feel like enough.

The Ghost of Broke Past

Your brain doesn’t care about your current bank balance nearly as much as you’d think. It cares about patterns — specifically, the patterns it learned when the stakes felt highest.

If you grew up watching money disappear, if there were months where dinner got quieter and your parents got tenser, your nervous system encoded a lesson: money is unstable, and you must stay alert. That lesson doesn’t expire when your salary crosses a comfortable threshold. It stays embedded, running in the background like software you forgot you installed.

In The Body Keeps the Score (2014), Bessel van der Kolk explains how traumatic and high-stress experiences get stored not just as memories but as physiological states. Your body remembers scarcity even when your bank account has forgotten it. That knot in your stomach when you spend on something nice? That’s not financial prudence. That’s a trauma response wearing a sensible disguise.

A 2018 study published in Psychological Science found that individuals who experienced financial hardship in childhood showed heightened cortisol responses to financial decisions even decades later — regardless of their current income level. The stress response had become structural, not situational.

This is why earning more doesn’t automatically fix the problem. You’re not dealing with a math issue. You’re dealing with a nervous system that learned its lessons in a different economy — the economy of your childhood kitchen.

Lifestyle Creep Isn’t Greed — It’s Compensation

Here’s the pattern nobody warns you about: you start earning more, and instead of building wealth, you start spending at your new income level. New car. Better apartment. Nicer restaurants. Not because you’re reckless, but because some part of you is trying to prove — to yourself, to your past — that you’ve made it.

In The Millionaire Next Door (1996), Thomas Stanley and William Danko found that high earners who grew up in lower-income households were significantly more likely to overspend on visible status markers than those who grew up in wealth. The spending wasn’t about enjoyment. It was about distance — putting as much space as possible between themselves and where they came from.

In my opinion, this is the most misunderstood pattern in personal finance. We call it “lifestyle inflation” and treat it like a discipline failure. But it’s often an emotional one — a person trying to heal an old wound with a new purchase. The fix isn’t a stricter budget. It’s recognising what the spending is actually for.

In November 2023, a report by Empower (formerly Personal Capital) revealed that 59% of Americans earning over $100,000 per year still described themselves as living “paycheque to paycheque.” High income, zero margin. The scarcity mindset doesn’t vanish with a bigger number — it just finds new ways to spend it.

The Permission Problem

There’s a subtler version of this that doesn’t look like overspending at all. It looks like under-living.

Some people who grew up with scarcity don’t inflate their lifestyle — they refuse to enjoy their money at all. They hoard. They deny themselves. They feel guilty buying a quality pair of shoes even when they can comfortably afford it. Every purchase triggers an internal audit: Do you really need that? What if something goes wrong? You should save that instead.

In Mind Over Money (2009), Brad Klontz and Ted Klontz call this “money vigilance” — a hyper-cautious relationship with spending that looks responsible on the surface but is actually driven by anxiety. Money vigilant people often have strong savings, but they can’t enjoy the security they’ve built. The fear never converts to freedom.

This is the scarcity mindset in its quieter form. You’re not broke. You just feel broke. And that feeling governs every decision.

If you ask me, learning to spend intentionally — to actually enjoy what you’ve earned without guilt — is just as important a financial skill as learning to save. Both require you to override old programming.

Your Peer Group Is Programming You

You might have upgraded your income, but have you upgraded your financial environment?

The people around you shape your money normal. If everyone in your circle complains about being broke, avoids money conversations, and treats investing like something “other people” do, that becomes your baseline — no matter what your payslip says.

In Who’s in Your Room? (2018), Ivan Misner and Stewart Emery argue that the people you allow into your mental space determine the ceiling of your growth. It’s not about ditching old friends. It’s about intentionally adding exposure to people who think about money as a tool for building, not just surviving.

In August 2024, a Vanguard behavioural finance survey found that individuals who had at least one close friend or family member who openly discussed investing were 2.4 times more likely to have started investing themselves. The scarcity mindset is socially reinforced — and it can be socially disrupted too.

A 2022 study in the Journal of Economic Behavior & Organization found that financial behaviours are significantly influenced by peer norms, with individuals adjusting their saving and spending patterns to match the perceived habits of their social group — even when those perceptions were inaccurate.

Rewiring the Default: Small Shifts That Stick

You can’t argue yourself out of decades of conditioning. But you can build new defaults — slowly, deliberately, one micro-decision at a time.

In Thinking, Fast and Slow (2011), Daniel Kahneman describes how the brain defaults to fast, automatic thinking (System 1) for most decisions, including financial ones. Changing your money mindset means deliberately activating slow, rational thinking (System 2) — and the easiest way to do that is through environmental design, not willpower.

Here’s what that looks like in practice. Automate your savings so the decision is made before your scarcity brain can intervene. Set a calendar reminder to check your net worth monthly — not to judge it, but to normalise looking at it. Unfollow three social media accounts that trigger comparison spending this week. Have one honest conversation about money with someone you trust this month.

In Atomic Habits (2018), James Clear makes the case that identity change precedes behaviour change. You don’t “try to save more.” You become someone who builds. The shift sounds small. It’s not. When your identity updates, your decisions follow — not because you’re forcing them, but because they align with who you now believe you are.

In my opinion, the single most powerful thing you can do this week isn’t financial at all. It’s sitting with this question for ten honest minutes: What would I do differently if I truly believed I was financially safe? Write down what comes up. The gap between your answer and your current behaviour is the scarcity mindset in action.

Where to Start

Your income changed. That’s real. But the way you relate to money — the flinching, the guilt, the quiet dread — that’s running on old code. Code written by a younger version of you who was just trying to survive.

You don’t need to be angry at that version. They did their best with what they had. But you don’t need to keep living by their rules either.

Start by noticing. Notice the tightness when you spend. Notice the stories you tell yourself about what you deserve. Notice how your body reacts to financial decisions before your mind catches up. That noticing — that tiny gap between reflex and response — is where the scarcity mindset starts to lose its grip.

You’ve already done the hard part of earning more. Now do the quieter, harder part: letting yourself believe it’s yours to keep.
