It’s no secret by now that the recent spike in American inequality, and the gains rapidly accruing to those at the upper end of the income distribution ladder, are driven in large part by “financialization”—the growing scale and profitability of the financial sector relative to the rest of the economy, and the shrinking regulation of its rules and returns. The success or failure of the financial sector has a disproportionate impact on the rest of the economy, especially when the combination of too much speculation and too little regulation starts inflating and bursting bubbles. And its returns flow almost exclusively to high earners. An overcharged finance sector, in other words, breeds inequality when it succeeds and when it fails.
