Have the tories forgotten that they do actually need tax money to, you know, pay for shit?
I think their plan is probably to pay for as little shit as possible. Shrink the state, slash public services etc.
The rich will be paying less tax so will have plenty of money to pay for private education, private health care etc. And as far as the Tories are concerned, the poor don't matter anyway, so they should just accept whatever meagre crumbs are thrown their way and be bloody grateful that they get anything.
