Why soaking the rich is hard to do

From an op-ed in the Wall Street Journal, on why raising state taxes on the rich doesn't quite pan out the way the big spender politicians think it will:

With states facing nearly $100 billion in combined budget deficits this year, we're seeing more governors than ever proposing the Barack Obama solution to balancing the budget: Soak the rich. Lawmakers in California, Connecticut, Delaware, Illinois, Minnesota, New Jersey, New York and Oregon want to raise income tax rates on the top 1% or 2% or 5% of their citizens. New Illinois Gov. Patrick Quinn wants a 50% increase in the income tax rate on the wealthy because this is the "fair" way to close his state's gaping deficit.

Mr. Quinn and other tax-raising governors have been emboldened by recent studies by left-wing groups like the Center for Budget and Policy Priorities that suggest that "tax increases, particularly tax increases on higher-income families, may be the best available option." A recent letter to New York Gov. David Paterson signed by 100 economists advises the Empire State to "raise tax rates for high income families right away."

Here's the problem for states that want to pry more money out of the wallets of rich people. It never works because people, investment capital and businesses are mobile: They can leave tax-unfriendly states and move to tax-friendly states.
...
Updating some research from Richard Vedder of Ohio University, we found that from 1998 to 2007, more than 1,100 people every day including Sundays and holidays moved from the nine highest income-tax states such as California, New Jersey, New York and Ohio and relocated mostly to the nine tax-haven states with no income tax, including Florida, Nevada, New Hampshire and Texas. We also found that over these same years the no-income tax states created 89% more jobs and had 32% faster personal income growth than their high-tax counterparts.
...
We believe there are three unintended consequences from states raising tax rates on the rich. First, some rich residents sell their homes and leave the state; second, those who stay in the state report less taxable income on their tax returns; and third, some rich people choose not to locate in a high-tax state. Since many rich people also tend to be successful business owners, jobs leave with them or they never arrive in the first place. This is why high income-tax states have such a tough time creating net new jobs for low-income residents and college graduates.

Those who disapprove of tax competition complain that lower state taxes only create a zero-sum competition where states "race to the bottom" and cut services to the poor as taxes fall to zero. They say that tax cutting inevitably means lower quality schools and police protection as lower tax rates mean starvation of public services.

They're wrong, and New Hampshire is our favorite illustration. The Live Free or Die State has no income or sales tax, yet it has high-quality schools and excellent public services. Students in New Hampshire public schools achieve the fourth-highest test scores in the nation -- even though the state spends about $1,000 a year less per resident on state and local government than the average state and, incredibly, $5,000 less per person than New York. And on the other side of the ledger, California in 2007 had the highest-paid classroom teachers in the nation, and yet the Golden State had the second-lowest test scores. [emphasis added] ...

Read the whole thing here. Of course, I would venture to guess that most folks, except big government politicians and leftie think tank intellectuals and economists, intuitively know this. If you tax something, you get less of it. Why is that so hard to understand?
