While I think that the private production of goods should not be nationalized, you should have strong government watchdog groups making sure that various companies "play fair" when it comes to things like labor rights, enforcing antitrust laws, or enforcing pro-consumer standards. This is because the larger a company grows, the more its political power increases as it dominates the market share as well as its ability to hire lobbyists to influence politicians to write laws in its favor.
Off of the top of my head, I think that everybody should be entitled to a certain minimum standard of living be it from a basic income to work guarantees, etc. I am not sure what the optimal combination of social programs should be, but I do think that should include things like healthcare, basic housing, and a livable wage, much like how every citizen is guaranteed free use. of emergency services like police, fire protection, and military security
I realize the latter is rather controversial with some people, but when you have fields or parts of the country that have a limited number of employers, I.e. monopsony, it is much harder for employees to get a decent wage as employers do not have much competition with each other for labor. Also, we will have to have some sort of safety net for all of the people that are going to end up losing their jobs as automation and AI becomes more and more commonplace instead of just letting its owners give most of the populace a giant middle finger in terms of wealth inequality.
As with any system, you will always have people that will abuse it or allow them to be lazy, but I think that is a risk that you will have to accept vs. letting some people fall through the cracks.
