It seem to me that China choosing to subsidize industry it is not so different than the US choosing to subsidize Roads, Autos and OIL.
In both cases it does seem to work splendidly as intended.
Other than political inertia (or economic reasons far beyond my ability to fathom) there is nothing to stop the US from following suit.
I accept "free market" is a term of art probably from before global trade reality and could be narrowly redefined to mean whatever one wants (or wanted when it was coined) but in my ignorance I see it simply as free to choose actions and responses.
But I am far far away from opinions I am qualified to hold, think I will shut up now.
I do know liberal is used as a derisive term by the people we (US) are being led by which leads me to cognitive dissonance parsing your statement.
