Yeah, we're not going to nationalize the entire economy because that's really stupid. Our tax dollars reach every nook and carny of the economy, but that's fine. Tax dollars are meant to be used in a way that makes the country operate safely, smoothly, and reliably. A lot of this is done by putting the money back into the economy in the form of subsidies, welfare, wages, and government contracts. It's fine for the government to pay a business to provide as long as the business is offering fair market prices and they're delivering an acceptable product or service. The tax money that goes into such a business doesn't just go to the shareholders, it also goes to everybody else as well.

That being said, shareholders can be scumbags, I'm with you there. If they are clearly conducting unethical behavior or illegal behavior then they should be immediately cut off. This includes things like delivering unacceptable products and services by cutting too many corners or committing fraud to take more tax money than they should or trying to scheme to monopolize and so on. These types of shareholders should've receive bailouts or awarded government contracts, they should be thrown in jail. But we shouldn't nationalize the economy because some shareholders are crooks.
