@Gorbles You keep avoiding naming any nations running or that have run a successful socialism based program and are now dwelling on the whole "what is socialism question". That is why I've said define it any way you want and just point out what you have seen as a success story. I'm not looking to argue over your definition. You don't even have to define it. Just give me some examples of it's success. I can figure out from your examples what you mean by success and the real world outcomes you are looking for.
Also it is worth to keep in mind that business don't have any more reason to want to pay their shareholders rather than workers and many don't pay their owners anything other than promising prospecting future growth and instead reinvest the money back into the business.
Keep in mind that share wealth is not an stable source of wealth, so these rich billionaires are only rich billionaires because their shares have a perceived value that make them billionaires but this can drop anytime.
The economy system used is thus more designed at creating rich and productive business rather than rich individuals, but people can still be seen as rich if they own a part of the business. Obviously this is pretty much the reason why it is so popular because it is very good at competing out any competing economic system.
Obviously this may sound very bad, but keep in mind that the people who benefit the most in the long term seems to be the poorest people who now can afford stuff that was unthinkable generations ago and that is largely caused by the economic system pushing the business to be as effective as possible which end up cutting prices on many goods, because whoever can sell the best goods at the lowest prices have a significant market advantage.
So business whose purpose is to maximize the wealth of their shareholders will eventually be outcompeted by growth focused business who spend their resources on maximizing productivity and that is a good thing for the economy.
Also keep in mind that countries like Sweden may have higher wealth inequallity than US and in many ways employ the "capitalist" system to a more serious degree but at the same time don't seems to have the same issues seen in US which have probably more to do with politics rather than pure economics. Basically US problem are US problem, not nessicarly "capitalist" problems, other countries manage to run maybe more "purer" form of "capitalism" but at the same time have more equality. Each country's problem needs to be looked at that country's perspective rather than some sort of global problem, because a good solution for one country may not work for another country.
Stuff like anti union is clearly caused by american culture or something like that. The "capitalist system" is not by itself anti union since it is concerned by productivity and stuff like unions that can keep workers happy and productive would actually be encouraged by the system, like the countries with best worker rights have many countries with similar economic systems as US. I read that a bank in South Korea actually tried to reduce how long their workers stayed and found out that by keeping workers away at night they saw a productivity increase, not decrease.
