Right now, we don't have a tax problem in America. We have a stupidity problem. Stop spending money on stupid shit, and maybe those evil Koch brothers will fall into line with your views on taxation.
Still, I agree we need a movement which will kick-out rent-seeking entities out of the spending loop. I wasn't so much agreeing with Buffet as using him as an example.
Also, I have no desire for that Koch brothers to agree with me. I would like them to go to jail but the odds look long.
And you, in turn, may be missing the point that this is ridiculous.
The question being batted back and forth between Democrats and Republicans is "raise taxes or print money?"
This is called a "false dichotomy." It's an indication that neither "side" has your interests in mind.
