Moving from the current situation to the situation you describe is impossible, because the UK has far too much debt and far too small an annual government income to pay for even the popular kinds of infrastructure spending, let alone the degrowth proposition you articulate. The millionaires really do take their assets and leave if taxes are raised and a Mossad-style international program to repatriate them in duffel bags would see the government that initiated it both out of power permanently and in cells themselves.
