As for the "attitude" argument, please don't argue that you don't get attitude from bored teenagers at privatized fast-food joints. The service industry hiring pool is fairly universal.
The whole point about privatization vs. government control is that private companies can do whatever government can better.

Not much is going on, on the left hand side of the map, with the exception of the far left.
