I didn't say we should abandon capitalism, I just think characterizing it as altruistic is extremely naïve. Capitalism might naturally tend towards the greater good better than other social systems, but it has no built-in guideposts that prevent destructive behaviour (see above).

Moreover, with the amount of ecological damage (mass, irreversible extinctions, global warming), indigenous genocide, slavery, etc. I'm not sure if being anti-capitalist is as "insane" as you put it. Global capitalism has given us advances in medicine, culture, reduced warfare, material wealth—but these advances haven't come without significant costs. Depending on what you value, capitalism could end up being a net-negative system.
