I thought so because, as you say, Chinas has nationalized banks, the airline industry — because they view them as important components to the nation.

I assumed we were not talking about the U.S. (and to a lesser degree European countries) since nationalization of the private industry is anathema to these countries. To be sure though I know nothing about nationalization sentiments in Europe these days.

you are confused they didn't "nationalizes" banks

they were never independent to begin with. you have a naive comparison and force it uncritically into this conversation.
