There are a number of examples of this in Argentina, where worker's cooperatives have done very well.But setting aside all the political bullshit, dog whistles, and lies, all socialism means is that employees own the companies they work in.
They have a long history with this type of employment, contrary to a country like the United States. But that has absolutely nothing to do with the relative perceived "success" of both of those countries. Those issues are a lot more complex. As most issues are.
My wife does research with groups like this in Brazil, and what you say is absolutely correct. It is nothing more than your statement. The work satisfaction, engagement, mentality, quality of life, etc. are all quite high in these examples. It's not very comparable to a standard work agreement in places like North America or Europe. There are exceptions, but it is a great model.
Unfortunately, there is a lot of blowback to this from powerful interests. Obviously. They have a very strong interest in attaching labels like "communism" or "socialism" with all of their baggage that is propagated to discredit a model that impacts their wealth. If that is surprising to anyone, well, I don't know what to say. Maybe try reading about the issue in depth from highly informed sources rather than watching the news or getting a line from Facebook or Twitter. It's neither a "left" or "right" issue. It's just business... man. Some people want to make a shitload of money. The playbook for doing that is pretty well established. Empowering the workforce is not printed in that manual.
I worked in Russia for a joint venture. Many an old Communist informed me that "capitalism" (black marketeering), was the only reason the USSR lasted as long as it did. The Communist party leaders understood they couldn't deliver the goods and if the generaql population didn't get what they needed ...
The USSR had nothing to do with empowering workers. I'm sure you don't genuinely believe that. If by "capitalism", you mean outright theft and lies, then I agree with you. That's how it works.
I read an interesting book that touches a little on this called "Red Alert". In the United States, they have an act named after the lawyer in Russia it concerns called the Magnitsky Act. It's an interesting read to understand a little more about what those "capitalists" were up to.
