That is a nice simplification, but it makes it sound like something that can just emerge gracefully within a market economy. There are employee-owned companies, for instance, and if that's all that's needed for socialism to work, then it would spread and show us all the benefits of socialism.

But the benefits are either not there or not amazing enough to spread. I'm left feeling like you left out the controversial parts, and I suspect that when you get into the details, there's lots of room for complicated power dynamics and ownership rules, perhaps much worse than non-socialist alternatives.
