I like the idea that each tax $ gives you a vote on what to spend it on.
The rich will naturally want to reduce their taxes, but then in doing so they will have less influence over government expenditure, so they won't want to reduce it too much.
On the surface this sounds nice, but you're probably not comparing how much you earn to the rich. Unless you're on $1m/pa salary, I don't think you realize just how little you have to vote with.
Oh it's true it would be bad for me while I'm poor, but I don't plan on staying poor forever, so I still like the idea.
That's a very bad outlook to have and the downfall of many conservative ideas. The poor matter very much and ensure that the rich stay rich. You should abuse them or not give them a voice, because it leads to very bad outcomes.
Additionally, upward mobility in this country is dead. If you weren't born rich, you'll never be rich.
