Nick Note: Let me see if i understand this. People will stop making money because their tax rate goes up? Does that make any sense. So what are the funds and traders going to do? Not trade and get a hot dog wagon. This is simply hysterics and stupidness. Do not let them make youa asshole Through the years the capital gains tax rate has risen and fallen. its a political football. See the historic chart of the capital gains tax rate
the chart is a little hard to read its the red line we are looking at. In 1954 the captical gains rate was 25%. In 1977 the rate was 40%. In 2010 it was 10% and now its 22%. So as you can see its a political yo yo. But here is where it gets interesting. the next chart is the capital gains tax rate and the stock market. 
The black line is the long term capital gains tax rate. at the time of the 1929 stock market crash the rate was 10% coming off of a 1920 high of 75%. During the 1950’s and 1960’s it was around 20%. When they lowered the rate in the 1980’s the rolling average total return of the stock market dropped…. the green line is the total individual marginal tax rate. As you can see their is no correlation to stock market performance on a total return bases and ANY tax rate… This is just the lobbyists lining up to collect fees from both sides of this tax debate……
