A short lecture
From Newsweek:
The presumption implicit in the criticism of growing economic inequality is that society's income is a given and, if the rich have less, others will have more. Up to a point, that's true. The government already redistributes much income, often for the good. During the boom years, companies might have been less lavish with top executives and slightly more generous to other workers or shareholders. Some new fortunes stem from self-dealing and financial razzle-dazzle, not the creation of real economic value. It's just deserts that some of this wealth has evaporated.
But the redistributionist argument is at best a half-truth. The larger truth is that much of the income of the rich and well-to-do comes from what they do. If they stop doing it, then the income and wealth vanish. No one gets it. It can't be redistributed because it doesn't exist. Everyone's poorer.
