The US spends considerably more on K-12 than the rest of the developed world. It isn't obvious to me that this allows you to avoid the problem of unreasonable cost.

The U.S. also has one of the lowest tax rates on the rich and the biggest military budget in the world.

With the proper reshuffling all most Americans would see are new opportunities to better themselves, their families, and the economy

That's an option, but not one that most Americans would support today, and probably not tomorrow either. At least not after you tell them what it would mean for taxes. All the pithy internet retorts to the contrary won't change this fact.

I worry that you don't understand how hard it is to raise taxes in the States. It hasn't been done in a substantial way for close to half a century. The trend has been rather the opposite.

Taxes need to raise on the rich. That is all.
