I asked my co-admin once if he thought Capitalism was evil, he's usually extremely careful with his words. He responded with "it might be".
It seems to have a lot of real problems, wealth inequality, human exploitation, environmental destruction. I think countries that have a mixed system, where it's part capitalist and part socialist tend to do better in most metrics. I wouldn't want to live in a country without socialised medicine, socialised education and pretty strict environmental restrictions.
