This is some of the rhetoric the Leave campaign used to garner votes, but none of it is what it was supposed to accomplish.
The architects of Brexit were proponents of William Reese-Mogg's ideology of the Sovereign Individual, which basically states that the wealthy should be above the law and outside the pervue of the state. It also calls for the collapse of democracy, via the withholding of the rich's wealth from the state via tax immunity.
It's still unclear whether the Sovereign Individualists will succeed in their goals, but they haven't failed yet, and Brexit was a necessity hurdle on their journey.
