So you're agreeing that a business person will invest if they see opportunity to make money.
A 25% tax rate is not going to stop any significant amount of investment. The uncertainty of what the rates are going to be are a far bigger roadblock to investment than the actual rates themselves. |
Yes, they will invest when they see an opportunity. They're also only likely to invest if they feel their investment will return X%, either because they will wait for another opportunity or, simply, feel the investment may not be worth their time.
An increase of tax rates will have a material effect on their real-cash ROI and in instances with push investments from above X to below X, and thus decrease investment.
I'm not saying I don't think capital gains rates should be raised. I think it's something worth looking into but the basis of your argument is flawed.
