Oh sorry, when I said nationalisation I meant the process of creating public revenue? Like you take the post office, or infrastructure, or natural resources (I hear people might want to see a change of management in the coal industry for instance), and you have the state manage it without the shareholders.

So everyone keeps their jobs, it's managed with very good attention to welfare and regulation, and then all the profits that would go to investors just lands in the national coffers.

I think it's good because it can then subsidise the tax burdens of ordinary citizens, which creates a constant and compounding stimulus effect just by default, so that way you won't have to throw a bunch of money at every emergency, you just sort of create passive stability overtime as people are permitted to set up savings and circulate money.

Plus it would just mean more disposable income to the average person and an increase in quality of life, which in a nicer world would be the first priority rather than something you have to sneak in at the end.
