Maybe, but since the US gov only has very limited legislative jurisdiction, district of Columbia, federal enclaves, "territories and possessions of the United States", and areas within the several states of the unlon specifically ceded to federal authority, post offices and roads, it was powerless to do anything to "correct" such a "problem" that clearly resides within the bailiwick of the States. So if the national government did nothing about it, it was because it didn't have authority to do anything about it. That is what "self-government" is - not relying on somebody else like a fedgov to do things for ones-self , in the true spirit of America, which is (was) self-sufficiency. Unfortunately the people are less strong, and have become conditioned into believing someone else ought do their dirty work for them. I'm different, but only because when I trust others most almost always fail. Many believe the "constitution" gives them "rights", but it doesn't. Example, there is no 1st amendment "right" granted by government that gives people "free speech". Most people don't understand that simple concept, unfortunately.
