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

You know, without China there is no Wal-Mart and without Wal-Mart there is no middle class and lower class prosperity in the United States.

It has always amazed me how tax cuts don't work until they take effect. Mr. Obama's experience with deferred tax rate increases will be the reverse. The economy will collapse in 2011.

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.

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.

The income effects in an economy always sum to zero.

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.
