>Have you never known conservatives wanting to lower taxes, deregulate the economy, and decentralize decision making?

I know its not conservative or liberal, it depends how you look at it. Deregulation of markets was seen as liberal at one time, devolution is pretty well supported except by some that support strong central government control, and lower taxes is often seen as American conservative, instead of offering services that they skim, or taxing you and giving you back more money (lol) they just won't take it in the first place. Milton Friedman's negative income tax is a beautiful way to help the poor without sudden cutoffs for when they try to become wealthier too.

I would say that these labels aren't as useful as top down control (big government, tell people what to do) or bottom up control (power to the people, let them do as they want to). Both can be useful for different reasons. The ozone hole and banning freon was top down but the tragedy of the common would mean it would never get fixed. The federal government also shouldn't raid dispensaries and prevent weed smoking.
