Funny you should ask that. I am one of those Forbes subscribers, and I do trade stcocks quite a bit. Does stock trading actually contribute anything tangible to the economy? That is open to question. Am I going to be happy about a tax on every trade? Naturally not.

Thankyou, you may have bought and sold some stocks I bought and sold to you. Pretty nice system.
If you bought some stock of mine, thanks for buying it. I saw the price on the ticker, didn't you? We agreed on the price? So what if some schmuck sold it to me two years ago at half the price I sold it to you. In that case I will pay The Obammunist 15% on the gain.
