The story in one scene

Imagine ten people around a table. One person calmly stacks eight slices on their plate. The remaining nine are left staring at two slices and a pile of crumbs. That’s not a morality play; that’s a data portrait of our era. Your job isn’t to hate the person with eight slices; it’s to get your own slice-engine working: build ownership, raise earnings power, and protect downside – while backing rules that make a fair game possible.

In the real world, the “one person” is the richest 10% of people on Earth; the “eight slices” are roughly ~78% of all household wealth; and the “nine people with two slices” are the other 90% sharing the remaining ~22%. This isn’t a slogan – it’s what the best global datasets show. – Our World in Data

The picture behind the pizza

How many people are we really talking about?

Zoom out from the table: there are a little over 8.2 billion of us on the planet today. If you split the room into tenths, the top 10% is roughly ~820 million people, while the bottom 90% is about ~7.4 billion. That headcount is why the pizza scene feels so tense – because the line between “one person” and “nine people” actually maps to hundreds of millions versus billions.

How much wealth is in the pie – and is it growing?

Now look at the pizza itself. Despite a choppy economy, the pie kept getting larger: global personal wealth rose about 4.6% in 2024, according to UBS’s latest Global Wealth Report. Their sample covers 56 markets representing the vast majority of world wealth, with the U.S. and mainland China accounting for more than half of that total. In short: the oven is still baking bigger pizzas – even if most people aren’t tasting more. UBS

Who holds what share?

Back to the table: who’s holding the slices? Using the World Inequality Database series (compiled by Our World in Data), the richest 10% of people hold about 77–80% of global wealth in recent years; the bottom 90% split the remaining ~20–23%. That’s the 8-slices vs 2-slices picture in hard numbers – and the reason our metaphor lands. Our World in Data

Why this matters to you (not just economists)

Prices, power, and policy

When wealth concentrates, the prices of life’s big tickets (housing, education, healthcare) tend to drift away from median incomes. Political influence concentrates too, shaping tax rules and public investment that touch your commute, your clinic, and your child’s classroom. (UBS documents where wealth is growing fastest; OWID/WID show concentration at the top persists.)

Your upside depends on ownership

Over decades, wealth growth comes from owning productive assets – broad market equity, business stakes, skill equity (higher earnings power), and sometimes real estate. If you only sell time, you’re playing a tougher game in asset booms. (Context from UBS.)

Volatility hits unevenly

People with buffers (savings + diversified portfolios) can keep buying during downturns; those without may take on costly debt or sell at the bottom. That widens the gap.

What you can do this month (practical, not preachy)

The goal isn’t to rage at the table host – it’s to build your own slice-engine. These moves are deliberately small, repeatable, and protective.

Build a “Two-Account” Cash Flow

How: Keep two checking accounts: Bills (rent/mortgage, utilities, groceries baseline, debt minimums) and Everything-Else (weekly spend). Route income to Bills; auto-transfer a fixed weekly amount to Everything-Else.
Why it works: Guardrails beat willpower. You get instant clarity on essentials, fewer surprise overdrafts, and a natural limit on impulse spending. Raise or lower the weekly transfer as life shifts.

Buy Broad Ownership, Consistently

How: Automate small buys (weekly/monthly) into a low-fee global or total-market index fund available in your country. Start tiny; increase your contribution 1–2% each quarter.
Why it works: You accumulate ownership – the main engine of long-term wealth – without timing the market. Contributions compound quietly in the background. (Educational, not investment advice.)
Mindset: Think “habit first, amount second.”

Raise Your Skill Equity

How: Pick one skill that predictably moves your pay within 90 days (e.g., SQL + dashboarding, AI-assisted workflow building, persuasive writing for sales/ops, or a targeted certification). Ship one artifact per month – a mini-portfolio piece (case study, repo, Loom walkthrough).
Why it works: Higher earnings power is the income side of compounding; artifacts convert learning into leverage for pay raises, freelance work, or role changes.

Tame Costly Debt

How: List balances by APR and run a debt avalanche: pay minimums on all, then throw extra at the highest APR. Calendar two rate-reduction calls per year (ask for hardship/loyalty APR cuts).
Why it works: A small APR drop can save months of payments. Avalanche prioritizes math (interest) over emotion (balance size).

Build Slack

How: Target 3–6 months of core expenses in a plain high-yield savings account. Automate a post-payday transfer (even €10/£10/$10 to begin).
Why it works: Liquidity is optionality. Emergencies stop becoming wealth killers and you avoid high-interest debt and can keep investing through downturns.

Use Collective Power

At work: Advocate for salary bands and transparent promotion criteria; share comp ranges with peers. Transparency lifts negotiation power for everyone.
In your city: Support policies that expand ownership access – portable retirement vehicles, fair housing supply, childcare that keeps earners in the workforce.
Why it works: The imbalance is systemic. Personal moves matter more – and last longer – when the rules of the game are a bit fairer.
