Name the industries which were created by the state in the first place*. Meet the new boss, same as the old boss.
Nationalised industries aren’t owned by the people, they are owned by the government/state. The people, and even the workers in them, don’t have much if any say on how these industries are run, in the private or public sector. Ask Stainsey, he works in the public sector, as I’m sure others on here do. I have worked in the public sector, private sector organisations and for myself and in partnerships. Only in the latter two did I have any sense of control or ownership, and in both I worked much harder.
The only influence we have over public or private sector concerns is as individual consumers, in other words minimal unless we act collectively. Which we very rarely do, because we have delegated our decision making agency upwards through believing, or being brainwashed into believing, that parliamentary democracy is the one true, real form of democracy.
* the ones that spring to mind are prisons, the police, the armed forces, customs and excise. The instruments of state control.
