I find this utterly baffling. You're a non-dom and you're complaining that removing that status will mean you have to pay so much tax that you'll leave. Right, well...
From what I've seen, the evidence that the super-rich actually do leave when taxes go up isn't there. So you might leave, but most of your fellows will pay more.
If you aren't paying your tax at the moment, then your argument that you have value to the country is essentially trickle-down economics. You have money, therefore you will spend it or give it to others. Trickle down has been shown to be bullshit.
So. You will leave and take your very small contribution with you. Fine. Most of your friends won't, they will compensate for the loss of your (to you) pittance. If you don't want to pay your share like everyone else, then you are not a loss to this country when you leave. Piss off and don't let the door hit you on the way out.
So who wins from the abolition of #NonDom status... the Treasury?... well maybe, but the immediate winners (as ever) are going to be the #lawyers & #lobbyists employed by the rich to game the (new) system, or try to change its character.
But where will all of those donations to the Conservative party come from? His ‘colleagues’ will have him wrapped in a straitjacket, sectioned and whisked off to a remote Scottish Island (the preferred place of exile for London these days) before he can put pen to paper.
It's just about the only thing Labour have not u-turned on as well. For now
