I've yet to see a single valid objection as to why LVT (Land Value Tax) should not be the primary tax, yet it's nowhere to be found in the political dialogue. Such a shame that the majority of the tax burden instead falls on the working class while the landowners get a free ride.
It actually makes much more sense to use a uniform sales tax: (1) If you spend more, you're taxed more. Obviously this is better for poorer people, who spend less, but also for rich yet reserved people, who keep most of their money in the bank (which lends it) and are earning an income (=productive). Both will not penalized. (2) It's much hard to raise, because people will just stop buying stuff, which is much easier…
This goes against just about every standard defense of the ability to be rich: that rich people are job creators, that they power the economy by buying things, etc. Why should we discourage them from employing people and buying things? I don't want a loan (that needs to be repaid) from a bank from a rich person, I want the rich person to either employ me or buy goods and services from me.
Actually, that's another point - does employment incur your "sales" tax? If not, it's more advantageous to hire a private chef or driver than to pay for a restaurant meal or a taxi trip, which makes the tax regressive - there's a discontinuity when you're able to hire someone instead of getting a service from a business.
