Individual companies being owned by their employees isn't socialism. For that matter, the Soviet Union wasn't socialist either - the workers owned nothing, the state owned everything. All the land, all the factories, all the manufactured goods.
Yep, that's what it leads to. But it all began with "good" intentions. They destroyed well-developed empire, took the land from the rich and see where it all now. Trust me, you don't want "to take money from the rich and spread them across poor" in USA, it sucks https://en.wikipedia.org/wiki/Dekulakization. Pleas, keep being a place where anyone can build a unucorn company and become rich af
Not individual companies, but at the wider scale. Socialism is an economic system, not the specific act of one group of employees owning where they work.
In the same way that China having private companies doesn't make it capitalistic.
