As for business taxes, they're way too high. They should be 0%.
Nonsense. Corporations need the government to be functional and well funded. Corps should pay the bulk of taxes to the state. Corps need courts, laws, police, fire, infrastructure, military, international agreements etc and all that vital service needs to be paid for.
I'd love to see a tax system that taxes idle wealth to the bone, does not tax working people at the median and below and have a major estate tax penalty on wealth over $40 million. End all the carried interest deductions, tax the holy hell out of short term stock gains to kill off the day traders, and stop writing tax policy that favors investors and start writing tax law that favors builders, workers, creators and other people who actually do the work in this country.
Right now, taxes in the USA are at historical lows. This is why we have a 23 trillion debt load and are still only paying out 1.2-2.5% interest.
