I think that control and conformity are good for a nation as a whole. Freedom is good for a person. (obviously this isn't a hard and fast rule)
There has to be something to be said for slavery. Without it, we wouldn't have the Great Wall of China or the pyramids or any number of other amazing things. Unfortunately, it probably wasn't all that good for the slaves.
At least with economic slavery we can have a relatively happy populace as well as all the benefits of slavery.
Does that mean everyone who wants freedom is selfish?
