We haven't properly educated people on the different levels of government in at least 20 years. So this shouldn't be a surprise to anyone.
We could easily fill a semester with American Government if we tackled things like who administers Medicaid.
Instead we have a single video (Mr. Bill), a movie showing D.C. is horribly corrupt (Mr Smith Goes To Washington), and a single chart showing the three branches, and then it's time to copy down more dates, names, and events!
