Maryland's Missing Millionaires

Wall Street Journal: The Maryland state revenue office says it's "way too early" to tell how many millionaires moved out of the state when the tax rates rose. But no one disputes that some rich filers did leave. It's easier than the redistributionists think. Christopher Summers, president of the Maryland Public Policy Institute, notes: "Marylanders with high incomes typically own second homes in tax friendlier states like Florida, Delaware, South Carolina and Virginia. So it's easy for them to change their residency."
