The 15% tax rate on long-term capital gains disproportionately benefits the wealthiest Americans. The rate should be eliminated as a separate rate from ordinary income, or at least be raised.
From Forbes: "The top 0.1% — about 315,000 individuals out of 315 million — are making about half of all capital gains on the sale of shares or property after one year; and these capital gains make up 60% of the income made by the Forbes 400."
Warren Buffer in his column in the New York Times: “I have worked with investors for 60 years and I have yet to see anyone — not even when capital gains rates were 39.9 percent in 1976-77 — shy away from a sensible investment because of the tax rate on the potential gain. People invest to make money, and potential taxes have never scared them off."
