Isn't the logical result of Federalism that we'll have fifty states all going their own way? Like the South can reinstate Jim Crow--if not outright slavery--and the Southwest can consider joining Mexico?
I think it means states can go their own way so long as they don’t violate the rules they agreed to when they ratified the constitution. I don’t think we require an all-powerful central government fine-tuning our lives for us as the only alternative to chaos.
