That first point sounds like you're anti-democracy. I'm not sure that's how you meant it, but that's how it comes across.
Also, the kind of socialism I'd like is the one that you'd find in Scandinavian countries like Norway. Free healthcare, free university, heavy public investment in clean energy, low poverty, livable wages. The only reason believing in that is called socialism is because every time I've tried to explain that that's what I think would be good, I get called socialist for it.
No, businesses, particularly multinational ones, are the ones breaking capitalism. Since the 80's they've effectively broken the trade union movement, meaning people have no means to collectively organise for higher wages. That's how you get Amazon's CEO being the richest in the world while his warehouse workers collapse from exhaustion and end up mentally ill from the stress of poverty. That's how you get Apple's CEO showing off the new iPhone while their workers jump out the windows of their factories. Unaccountable private power has flexed it's muscle to the detriment of the majority of people, and we need accountable public power to rebalance the scales in favour of average Joe. The power difference between today's financial elite and the man on the street is so vast it's a wonder the whole thing doesn't just flip upside down. Free marketeers claim that trade unions damage the free market, but I'd argue that unions are an important part of the market because they allow the labour force to set their own market rate for their work. Every other aspect of business gets to set their own prices, why shouldn't the workforce?
Also gender quotas and affirmative actions are slightly different issue. That's more about rebalancing from past injustices than it is specifically about the problems of capitalism.
