I think Labour has already pledged not to raise taxes, but let's play devil's advocate and pretend that they were going to slap a £2000 on everyone of working age.

Doing some fuzzy maths based on statistics I can find online from 2 years ago, that's roughly 45 million people, or £90 billion a year. Or to put in into the Brexit campaign's favourite terms, £1.7 billion per week going into public coffers.

I'm not suggesting such a flat structure would actually make sense as a policy, but that maybe tax rises as a concept aren't always a universally bad thing.
