Damn, son. EV with the uncut shit.That's all you need to say. The government's job isn't to "make money." That's called a tax. Unless your coworker thinks the government should just be a taxing machine until it removes all currency from the economy, then ... well, either way, your coworker appears to be an idiot. Not an idiot for being ignorant, but an idiot for opening his/her mouth and proving it.
(I realize this guy is misguided, but he's a nice person who seems intelligent enough at work--a little reasoned discussion can't hurt. However, I don't harbor any illusions of changing his mind.)
