If you like the post office and the Department of Motor Vehicles and you think they're run well, just wait till you see Medicare, Medicaid and health care done by the government.

There are 11 states in the United States that in the last 50 years instituted an income tax. So I looked at each of those 11 states over the last 50 years, and I took their current economic metrics and their metrics for the five years before they put in the progressive income tax... Every single state that introduced a progressive income tax has declined as an overall share of the U.S. economy.

People can also change the timing of when they earn and receive their income in response to government policies.

Let's take the nine states that have no income tax and compare them with the nine states with the highest income tax rates in the nation. If you look at the economic metrics over the last decade for both groups, the zero-income-tax-rate states outperform the highest-income-tax-rate states by a fairly sizable amount.

When you look at the world, everyone in the world who cares about his or her family wants to have a major portion of their assets in the United States because we are the growth country and the freedom loving country.

Government spending is taxation. When you look at this, I've never heard of a poor person spending himself into prosperity; let alone I've never heard of a poor person taxing himself into prosperity.

If you look at the performance of the zero-income-tax-rate states and the highest-income-tax-rate states, I believe a large amount of their difference is due to taxes. Not only is it true of the last decade, but I took these numbers back 50 years. And, there's not one year in the last 50 where the zero-income-tax-rate states have not outperformed the highest-income-tax-rate states.
