They leave.

In case you missed it, Britain announced recently that their tax hikes on millionaires lost them £7 billion, as 10,000 people in that tax bracket moved elsewhere – two thirds of Britain’s millionaires. And France just raised taxes on their millionaires, and one popular actor left – causing a bit of an outrage – with this parting shot: I am a free being, sir.

Democrats know this, but the current lot don’t want to raise taxes to raise government income, they just want things more “fair”.
