Funny you should bring up the VAT. In the back of my mind I’ve been worried that this concept will grow some legs. True enough about being regressive but I think it would come with a boatload of exemptions to help the lower incomes. And that plays into my previous concerns about a complicated tax structure.
By the way, I think there would be a lot less resistance to a flat tax above $50k than on all income levels.
Just to remove the record keeping alone I would pay more ! Shuush don’t tell Obama this. 😉
