Why a land tax? Many (most? all?) towns and cities have a real estate tax.
You forgot long term capital gains tax. There is no reason that the investor class should be paying a flat 15% tax. Critics will quickly jump up to say that we need to incentivise people to make long term investments in businesses, which I agree with, so short term capital gains should be taxed like gambling winnings.
Also, minimum wage can be addressed with a one time bump and after that, make tax brackets, 401k contribution limits, etc. multiples of the federal minimum wage.
