The French economist Thomas Piketty has a strong and obvious argument as to why the rich usually get richer and the rest of us not.
He points out that so long as the return on assets—of whatever kind—is at a higher rate than the rate of economic growth, wealth and income will flow to owners of capital, not to wage-earners.
If you see gross inequality as a problem, there are two possible solutions:
- Raise the top tax brackets to reduce the share of the capitalists.
- Increase the rate of economic growth to increase the share of the workers.
An economist named Gerald Friedman concluded that Bernie Sanders’ economic policy would produce 5.3 percent annual economic growth. Other economists say that is over-optimistic to the point of being crazy. But even if Friedman is right, it would still be less than the historic rate of return on capital.
If Piketty is right, it means economic growth alone will not stem the growth of economic inequality. It will be necessary to reduce return on capital, not to zero, but to a rate less than the rate of economic growth.
One way to do this is to raise upper-bracket taxes to 1950s levels. Regulation of interest rates and subprime lending would help. Prosecution of financial fraud and enforcement of antitrust laws might have an effect.
Historically, as Piketty noted in Capital in the 21st Century, there have been other ways in which concentrations of wealth have been destroyed. They have been destroyed by means of wars, revolutions and devastating economic depressions.
