What's the point of of a LT Capital Gain?

[Slamz]

So by Slamz reasoning, wouldnt everyone do that the second the government jumps the cliff causing a HUGE market selloff?

I think the sign would be gigantic market volume with little change in price. It's a huge sell-off but it's also a huge buy-in, assuming people are doing mainly what I said, which is sell and then rebuy. Or it's like someone else said, and they are selling off and staying in cash, perhaps in anticipation of a huge sell off...

I wonder if we could see a stock market crash mainly driven by fears--actually "hopes"--of tax concerns causing a sell-off. Everyone will be getting into cash hoping to see a crash so they can get back in.
