blaming capitalism is extremely useless
it is if that's all people do, but I think it is a necessary step to realize that we do live under a system that encourages an amoral allocation of resources. If people only ever shrug that off or treat it as intractable it will never change. Some would argue that it cannot be changed, but I think that just means they haven't read history.
Until it isn't because enough people realize it is inherently flawed and will never result in stability and they would rather die than relegate themselves, their children, and all their later generations, to indefinite servitude of an outdated economic system. Provided we don't kill our world first in our pursuit of endless profit growth.
