The engines of inequality: Why gaps widen on their own

Inequality does not fall from the sky. A few simple mechanisms widen it, year after year, without anyone deciding anything.

First engine, the most famous: a small formula. R greater than G.

It comes from the economist Thomas Piketty, in a book published in two thousand thirteen. R is the return on capital. G, the growth of the economy.

His idea: over the long run, capital often earns faster than the economy grows. And so faster than wages.

Say one hundred thousand euros of wealth earning five per cent a year. And a thirty thousand euro salary following an economy at one and a half.

At the start, this wealth is worth a little over three years of salary.

Thirty years later, the wealth weighs four hundred and thirty-two thousand euros. The salary, forty-six thousand eight hundred and ninety-two.

The wealth is now worth more than nine years of salary. With no extra effort. Simply because r beats g.

This idea is debated. Returns vary, taxes and crises destroy capital. But the mechanism is real.

Second engine: inheritance. When wealth weighs heavily against wages, what you receive counts more than what you earn.

In France, according to the Council of Economic Analysis, inheritance makes up about six tenths of total wealth.

In the early seventies, it was about a third. Birth weighs more and more on fortune.

Third engine: how value is shared. What a company produces is split between those who work and those who own.

Wages on one side, profits and dividends on the other. When capital's share rises, its owners benefit.

And capital is far more concentrated than work. Almost everyone has a wage. Few people have lots of shares.

Fourth engine, the most everyday: compound interest. It works for some, and against others.

Whoever is ahead invests. Ten thousand euros at five per cent, for ten years: sixteen thousand two hundred and eighty-nine euros.

Whoever is short borrows. Ten thousand euros owed at ten per cent, with nothing repaid: twenty-five thousand nine hundred and thirty-seven euros.

The same mechanism, in two directions. One sees their money grow. The other sees their debt grow even faster.

The twist: none of these engines requires cheating. They run by themselves, even in a perfectly honest system.

That is why inequality is a political subject. Slowing it takes a decision: taxes, education, credit rules.

At your scale, the lesson is the same. Time works for whoever owns, and against whoever owes.

Getting out of expensive debt before investing means switching sides in this mechanism.

R greater than G, inheritance, sharing value, compound interest. Four engines, one slope.
