The biggest - one of the biggest barriers to driving economic growth is the capital gains tax rate. I propose taking it to zero.

Reducing the tax burden is necessary to produce economic growth.

The data does not support that high-income tax cuts are the main drivers of growth, so I don't think that uncertainty over what the tax rate will be for someone that makes a million dollars a year has that big an impact on the economic growth rate in the country.

We need to lower tax rates for everybody, starting with the top corporate tax rate. We need to simplify the tax code. The ultimate answer, in my opinion, is the fair tax, which is a fair tax for everybody, because as long as we still have this messed-up tax code, the politicians are going to use it to reward winners and losers.

Here's the problem if you keep raising tax rates: You slow down economic growth.

Legislation to create a new 10 percent tax bracket, reduce the marriage penalty, cut the tax rate on dividends and capital gains, and increase the child tax credit have been essential elements in this economic expansion.
