What does "communistic states" have to do with anything? They were/are kleptocratic oligarchies that are so stratified that they have even worse class systems than capitalist states.
> My point is that system evolution via democratic process is much better than bloody revolution that left-wing quite often has on its mouth.
It was not evolution via democratic process that gave us the 8 hour day. It was not bloody revolution either, but plenty of blood has been shed during the fight for decent working conditions. People were outright killed. People were arrested. People were intimidated; blacklisted.
The current system is only as good as it is because our forefathers were brave enough to stand up and fight even when they had to break the law, and even when they in many cases risked their life to fight the conditions of the time.
And they had to: Plenty of people died because of the disproportionate powers of employees to dictate conditions. Such as the Triangle Shirtwaist Factory fire, where 146 people died when the factory burned because the employees kept the doors locked during working hours to prevent unauthorized breaks(!):
