Fiscal cliff and the invesmtnet tax rates

The question is how will the market is affected by the new (if no change) tax rate. Most of the small investors will not be affected. However, the market is driven by big boys. The pension and insurance part of the big boys may not be affected. Their rich clients will be. Beside seeing the actual effect, we can only estimate how many of these rich clients are.

The other argument of dividend stocks in retirement accounts works for some but not for most as they have to withdraw from these accounts eventually. I'm facing this problem eventually and I need to withdraw large sum before I turn 70 1/2.
