People of retirement age do leave; but probably not fast enough if you’re trying to “raise” taxes that way. That said, it depends on people’s total state tax burden. If it’s too high they will leave to lower tax burden states. This is one of those slow moving things like when corps were leaving NYC in the 80s. It’s hard to stop it. Adding taxes is too attractive. Eventually companies and people will have enough reason to leave. Many are not there yet. You will never have everyone willing or able to leave. But on occasion you get enough leaving so that a state is left with a potential which will not become realized.
