2/3. If the US pays more for health care and gets worse results why should we give them more money?
I don't think health insurance companies should be abolished by royal decree. I think the government should offer an alternative and when that alternative is 4x as dollar efficient the health insurance companies will die a natural death.
4. Your chart shows corporate tax rates have been flat for 50 years. Seems fine?
As an aside, I dislike the overemphasis on Federal spending and Federal income tax. The real question is federal+state+local spending and revenue.
I wish as a society we could work backwards. What services do we want to provide? How much will that cost? How do we pay for it? We've turned into a culture where some people thinking spending is good solely for the sake of spending. When politicians trumpet how much money they're going to spend rather than the benefits they're going to be provide I get very sad!
