Free markets suppose to compress margins, perfect market theoretically drive profits down to zero (aka involution). But you compress margin and you lose current western semi business model that is functionally monopoly suppliers/producers who can sustain 50%+ margins to keep their monopoly. Shed those margins down to 20% because competitor enters market, harder to fund R&D to keep lead, it's still "enough" to be profitable, but then western commercial companies have to think harder how to split that compressed margin between investors and R&D. Right now we know what this leads to. Investors get paid, companies beg for subsidies. Not that PRC companies aren't concerned, look at PRC stock capitlization, not nearly to the same degree.
Free markets? No, competition does that. Competition requires free markets but free markets don't guarantee competition.
