I still don't really see the argument. I mean, my assumption was that most parliamentarians and most parties simply didn't want to see Brexit happen at all, but they put it to a vote to shut up some right-wing Tories whose main reason for being pro-Brexit was some kind of flag-wagging nationalism, not for business or even robber-baron reasons.
And the votes for Brexit hardly came from "the elite". They came, in large part, from working class areas where the EU was perceived to have led to a lot of wage deflation and competition for jobs, and Brexit was also supported by the far more anti-capitalist left-wing of the party.
So, really, I cannot see where Frankie is coming from. It sounds like some kind of attempt to put conspiratorial, almost swivel-eyed simplifications on a complex problem, "I bet it's the elites trying to do something really horrible to people because of the elites' evil motives!"
