Let's assume, for simplicity, that for a successful government of any type to run, taxes must be assessed to the populace.
In what way would you assign those taxes? Currently America assesses taxes in a frighteningly complex manner that I honestly couldn't begin to explain. We've already had some talks about sin taxes (cigarettes, alcohol, prostitution) and people's general dislike of those, as well as people for and against flat taxes, progressive taxes, sales taxes, consumption taxes, environmental offset taxes, etc.
I'm asking because I can't really think of a simple, comprehensive, enforceable way to distribute the burden of running a government fairly among a nation.
Maybe we should go back to the Roman method of putting districts up for auction and having tax collectors bid on the right to collect taxes in those districts, and the tax collectors keep whatever they get above the auction price as their salary.
