Well, let's look at this logically:
1) We, as a society, have determined (through elections) that we want the government to pay for certain services.
2) There are three ways of paying for things: Printing, borrowing, and taxing.
3) Printing is risky. In severe recessions, a little printing isn't too terrible because it counteracts deflation, but in almost every other economic situation it should be avoided.
4) Borrowing isn't risky, but it is essentially the same as taxing. It's just taxing future generations instead of present generations.
5) That leaves us with taxation. So whom do we tax to pay for the government programs that our society has determined it wants? People who HAVE money to tax, or people who DON'T have money to tax? Should we get our milk from the cow or the bull?
