Oh, for the love of - those are all either reasonable or necessary.
Soldier? Fine, let's have no soldiers. Then we'd have civilians waging wars instead.
Prostitution? Get over yourselves, sex sells and if they wanna sell it, let em.
Politics? Can we forget the stereotyping for a minute and remember that politics is, I quote, "Politics is a process by which groups of people make collective decisions." IT'S FRIGGING DEMOCRACY, POLITICS IS WHY WE AREN'T LIVING IN ANARCHY!
Marketing? That's just getting you interested in a product, if you're stupid enough to buy something that you don't want or need, purely because of marketing, you deserved to lose your money.
Law Enforcement? Yeah, I'm not even going to answer that one. At least most people were smart enough not to vote for that.
Tax Collectors? The reason you can afford to have so damn much is because you have a government that can provide it. They can provide it because of the steady flow of cash.
If this wasn't a serious thread, I apologize, but I got the feeling that it was.
EDIT: ****ing psychics. In no decent civilized world should these people be allowed to claim theirs is a legitimate practice. The world would unquestionably be a better, safer, more wholesome place without them.
And child-prostitution-ring-leaders. Whatever you call them. If that's even a profession. Safe to say the world would be better without them to.
