"In 1982, bank lobbyist Alan Greenspan was appointed to head a U.S. commission to shift Social Security out of the public budget (where it was funded largely by progressive taxation) and fund it by user fees that fall on employees and employers. The aim was to privatize it Chilean style. Wall Street’s dream is to turn wage set-asides over to money managers to buy stocks and create a stock market boom (and in the end, siphon off commissions and push contributors into high-risk bets on the losing side of the deal with large financial institutions, Goldman Sachs style). In effect, Mr. Greenspan’s position was that Social Security should not be a public service. It should be a user fee, so that prospective retirees would pay for it in advance. Their savings were to be lent to the government to enable the Treasury to slash taxes on the higher income and wealth brackets. So the effect was to reverse the long trend toward progressive taxation. The upshot of the Greenspan tax increases (only on labor, not on wealthy earners) was to create a budget surplus for the Social Security Administration, enabling the government to cut taxes on real estate, on finance, and for the rich in general. Capital gains taxes in particular were cut in half."
