"Actually capital works well" - "Work well" needs to be better quantified.
Capitalism can work well at building personal profit. Maybe that works well in a nation of narcissistic individuals. Your primary motivation is to make money. This is at the expense of natural resources, individual health, national health, other people's wealth.
"Well the government can organize it" - this fails because in a capitalist system the public officials primary motivation is also personal gain. There are exceptions, but in general this sets up a system that basically means "make as much money as you can without blatantly hurting too many people or angering so many it cuts into profit"
Why is McDonalds legal? Why is pornography so prevalent? Why is Hollywood so stupid? Why is science corrupt? Why is our health care system a piece of shit?
The primary incentive for everyone is personal profit, at the expense of others. There is no cohesive societal glue except for an occasional bout of mutual fear over a new foreign enemy. New York doesn't give a fuck about you. LA doesn't give a fuck about you. Even your doctor and neighbors probably don't give a fuck about you. These people only tolerate you for the hope of making a buck off you. The "mass of people" are viewed upon like a lot of farm animals (but even more demeaning, many small farmers actually care about their animals) - and this applies the same to Communism. Medicaid / Social Security / Welfare / Foodstamps / etc don't exist in because the system cares, but because such systems have walled off a segment of the population to a specific voter bloc, plus it helps keep the natives calm so business can continue as usual (plus there's money to be made if you know how! EBT forces tax payers to subsidized Coca-Cola, Walmart & JP Morgan even if they don't want to shop there!).
If you're not aware of this fact, you're just one of the "suckers born every minute"
You may be able to hold up your own moral code and actually care about your community, but you need to be aware that the above takes primary precedent and your ways are nothing but an anomaly.
