Unfortunately, every single word of this is absolutely true.
It certainly is a tour-de-force rant, delivered in a single-take without any disfluencies. I wouldn't make it past the first sentence before fluffing my lines.
However, I disagree with one fundamental point i.e. Brexit means the poor want to stick it to the establishment.
If that were true, then the Tories wouldn't have been returned to government in the 2017 General Election.
Austerity has been around since the GFC, and since then the Tories have won TWO elections. In fact, they're STILL ahead in the polls. Thatcher, the archetype of crushing the poor, won election after election after election.
If the Tories represent the 1%, why are half the 99% voting for them?
My take is that the poor vote what the press tell them to. If The Sun says vote Tory, they vote Tory, if The Sun says vote Brexit, they vote Brexit. Right-wing memes are more successfully propagated.
Likewise, we've even seen Trump voters in The South say they'll vote for him again, even if their standard of living is going backwards. Tax cuts for the rich are still getting through, endorsed by the bottom of pecking order.
