Be careful how you think of this. TAX <severity> is not a "tax rate".
It is like saying "Let's go beat up the citizens for seven days and
see what kind of money we get." The more men you do it with, the more
likely you are to make some money. A "tax rate" of zero means you don't
go beat up the citizens.
