Actual born-Londoners aren't LARPing like this, they sold their shite family home for a million pounds and moved to Malaga years ago. They have their culture and they've taken it elsewhere.
After I get away from the old racist failed actor, I go to see my Korean colleague. He's just arrived in London and I want to see how he's handling the party. We'd been invited as fresh meat for some of the older, gayer attendees. We aren't aware of that.
The studio designs some piece of media to perpetuate the marketable concept of Real London, while the real London is hollowed out by hollow bankers or whatever. Not pulling on that thread. But the yuppies don't mind because they're free to iterate on Real London without any competition from real London because it's too concerned with its slow eradication. And there's nice flats to live in now or whatever. The yuppies can begin to inhabit their Real London.
