There essentially is not completely "Free Market" in the United States
The US has a mixed economy
There are people who don't know this?
There are a lot of people that don't. No industry in the US is completely Free Market. I doubt there's an industry anywhere in the world that is,
as Free Markets tend towards Monopolies, and monopolies are frequently more than willing to use political, economic, and military power to reduce competition. Without a referee, anything even remotely similar to a Free Market will deteriorate, with a referee, it isn't Free Market. Such is life.
