Does every state have the standard of slower vehicles drive in the right lane?

In my state when there's a road with two or more lanes going the same way, we have a rule/law: the left lane is a passing or "getting the fuck on" lane (if you will). Don't get me wrong there are undoubtedly some from my state that will be in this lane when they shouldn't be, but I see so many people from out of state that will be going slow, barely going the speed limit, moving slower than those behind them are in the left lane. They are just cruising along like there's not a bunch of cars speeding around them or blowing their horn indicating they shouldn't be in that lane. This doesn't seem to phase them, or give them the hint that they should move over.

So I'm just wondering is this not the standard rule for driver's in other states?
