More importantly, when Maryland "decoupled," so did huge numbers of successful Marylanders. We simply moved out of state, by last estimate some 10,000 of us. I personally know more than a dozen ex-Marylanders who are now residents of Delaware, North Carolina, South Carolina and Florida (most of us chose Florida because there is no estate tax or income tax.) Successful and affluent people are much more mobile than the poor and middle class. If Maryland had at least been reasonable about this tax, many of us would have stayed and continued to pay income tax and sales tax as well.
