I'm curious where you got this idea from. If anything, my university history classes looked at US history as a power struggle and certainly not through rose-colored glasses.

Sure, elementary education glosses over the state's transgressions and the like, but it doesn't seem exactly appropriate to go into detail about how native americans were raped and murdered by colonizers to a 9 year old.

Education teaches people to think critically, which is incredibly important to liberal society and, if anything, would encourage people to _not_ be obedient workers.
