Incidentally, I support taxes in general and think we need more taxes on a lot of things. But taxes add cost to specific activities, and so they should be used to reduce those activities. Now, we don't want the perverse incentive of government relying on tax revenue and thus otherwise wanting to promote the activity. So, we need to find a balance in all these things. But like taxes on stock-trading would be good. And we should probably increase property taxes and just do the simple thing where property tax rates go up the more properties an entity holds (that makes it harder for investment companies to buy up all the properties and gouge everyone with high rents).
But for all the justified complexity of tax policy decisions, sales taxes are the worst and should just be eliminated.
