I'm not here to debate whether free markets are good or bad, but governments have a privileged position versus private companies, and effectively operate above the law (again at least compared to private companies). Any government intervention takes us away from a free market, either a little bit or a lot, depending on the action. Apple is a private company. Anything it does is really part of the free market, at least in the original meaning of that as described by Adam Smith and co.
We’re talking about China subsidizing goods that it sells in another country. This is bread and butter “free market” behavior. Literally every company in the world does this one way or another.
My friend, what is so special about the government? If a company uses its massive profits in one area to crus competition by selling at a loss in another area, this is the free market, and when a government does it it is something else? I think you have not thought this through
A government has a monopoly on violence. A government has a monopoly on money printing and taxation. A government has a monopoly on the legislation. A government has far more human and financial resources than any other economic actor within its borders.
If a company goes out of business, people lose their jobs. If a government goes out of business, people lose their lives.
It is not a difference in degree, it is a difference in kind. There is a reason that economist distinguish between private firms and government.
