Obama Wants Higher Capital Gains Tax Rate: Too Far Or Not Enough?
Raising capital gains taxes from 15% to 20% is a step in the right direction, but they should just be taxed as ordinary income (exception below). The vast majority of this are not capital investments: it is me buying a stock from you and it doesn't provide the company with new capital except in the most indirect fashion. If the value increases, I make money. I should pay income taxes on it. We just have different ideas of the future value of the stock and its importance to each of us given our evaluation of our circumstances.
The argument for the lower rate sometimes turns on it increasing interest in the stock market and helping it grow. But I think we know enough now to realize that inflating bubble prices for the sake of increasing prices isn't what government policy should be doing. If we are going to support something, it should be something that produces tangible lasting value to the common good.
The exception I've argued for would be for true risk capital: investing directly in businesses and holding that investment a long time -- startups, and the like. But not regular stock trading.
Obama Wants Higher Capital Gains Tax Rate: Too Far Or Not Enough?:
The president's plan would raise the tax rate on capital gains and dividends to 20 percent from the 15 percent levels imposed by the Bush administration.
In his budget, Obama did take another action on capital gains tax by phasing out the elimination of such taxes for startup and small businesses. But, as pointed out by Ben Smith, the president had promised to do this upon taking office, but the cut was deferred in his budget to 2014.
