To your point, Erwin Lutzer wrote an excellent book, "When a Nation Forgets God - 7 Lessons We Must Learn from Nazi Germany". Highly recommend it.
What we have seen here is the establishment of an authoritarian, totalitarian federal goverment which has just been given the authority to do whatever it wants to do (this time by way of tax). Any competition in the insurance market will be completely wiped out and the path to single-payer is now clear.
Single-payer is the ultimate goal of the federal government as this will give them complete power over the citizens. The federal government, with complete control over healthcare, will ultimately decide on what care that each individual recieves. Doubt it? Look up "The Complete Lives System"
