Re: How would you change the U.S. tax system?

1A: Capital to be adjusted for inflation, i.e., you buy a house for 100k and sold for 500k, but 100k is now worth 200k, you are taxed in the 300k not the 400k. 1B: Dividends to be tax deductible for the corporation, to avoid "double taxation" It seems like the inflation adjustment would m...

This is why it can't all just be a 'popularity contest' - we need experts to decide where society's money is best spent, and often that involves long term planning and investment.
