Now, a half-dozen states in this recession-driven movement are nervously eyeing New York to see if it's wise to demand so much from people rich enough to have a second home in less taxing states — and for whom a change of address can be its own tax break.

Early data from New York show the higher tax rates for the wealthy have yielded lower-than-expected state wealth. Gov. David Paterson, who had always warned targeting the rich could backfire, fears that's just what happened.
