We won't
In all seriousness though, the world is now a very small place now and I'm less and less sure what the benefit of being in the UK is if you earn good money and don't want anything off the state. Especially considering under 35's like myself won't be getting a state pension, or at best it'll be means tested.
This is the bit that Corbyn and his merry band just don't get. HMRC is neither well resourced, nor smart enough to extract significant tax revenues from
the 1%. Much less the big multinationals. People will just up and move - or more likely, just move on paper. When you are that wealthy, what country you live, work and invest in is a choice, and no-one got to be that wealthy by choosing to give it away.
So, where will the burden of paying for the Corbynite Bright New Dawn
TM fall? It'll be on those under that 1%, anyone earning £40-100k, the 10% if you like. Those who are seen as less geographically mobile and an easier target, while still being "rich enough" for no-one to care how much they're taxed. I'm already at the stage where I see little point in pursuing a better job, because any gain I make will be (nearly) half due to the taxman. Corbyn's policies make the choice of whether to stay or go really very simple for us as a family.
I know that my wife & I, and others like me are seen as the "its alright for you" crowd who should just get our hands in our pockets and contribute a bit more and "don't let the door hit your ar$e on the way out" is a common attitude. That's fine, but for everyone that goes, the tens of thousands of pounds of tax revenue that gets quietly contributed every year goes with them. I've talked about this with a number of mu colleagues and friends, many of whom have worked abroad at some point before and will again if Corbyn gets in.

Yes I could do it myself, but its one job I prefer to farm out.
