Ask HN: How would you change the tax system in the US?

From my experience it looks like a system loaded with complexities, and loop-holes that only wealthy can take advantage of. The tax money, goes into a black box, that seems to function like a furnace.

I have friends that work in government, who acknowledge the bureaucratic mess that just wastes money.

I think we should all pay some predefined portion, but have the ability to change where we want our tax money allocated each quarter. Education, defense, infrastructure, health, etc. Everyone is happy, no one is skirting around their fair share, but each person gets to decide where their money goes. Granted, this might cause undershoot and overshoot in times of war, emergencies etc, but we could think of some clever way to mitigate that.
