Also, "only the super wealthy elite should be able to live in London" is very dangerous, since London dominates the arts, media, politics, finance, and many other careers. It shouldn't do, but it does, meaning people with careers and talent in those industries have to live in or near London.
Do you want to live in a world where the media is run exclusively by the wealthy upper classes and foreigners? (It already mainly is, but there are at least some regular people to stop it from spiralling completely out of control, and you want those people pushed out.)
Where ordinary working class and even ordinary middle class people are pushed out of the arts?
Where politics and finance are the preserve of the elite?
Where London becomes a ghost town and tourist attraction, and ceases to be a vibrant living city?
The biggest threat to the UK is how completely divided we are, and the way politicians try to weaponise and push that sense of division even further. The last thing we need is to be even more divided.
So no, my working class arse is going nowhere. I won't be forced out of my own home, abandon my career, and give the city of my ancestors over to the corrupt elite, and I won't be fobbed off with the idea I should settle for a crap life and no career for the privilege of maybe owning some shitty little terrace house.
Because it doesn't need to be this way. Vote in a government that's not entirely corrupt and doesn't act solely in the interest of the elite. Ban foreign investors from buying entire neighbourhoods that stand empty. Force foreigners and corporations to pay tax. Put restrictions on slum landlords and foreigners buying up swathes of our country for rent. (And those of you smugly talking about how cheap your rents are: if we don't stop this now, you'll be next.)
