To me it's equally as wild that you say such a thing when no system in human history did as much as capitalism to alleviate hunger and disease. In fact all other systems combined still can't touch the progress we've made to eradicate famine and disease while "under capitalism".

There are good critically examined rebuttals if you actually look for them beyond Wikipedia which is not designed for that purpose. I read a book recently called Socialism: the failed idea that never dies, and while it has a clickbait title, the arguments are pretty cogent as to why people throughout history want to enact socialism based systems and why they eventually fail.

> capitalism still kills millions of people a year with starvation and preventable diseases

as if somehow, it's the responsibility of those capitalists to ensure those starving people have food and diseases cured - for nothing in return.

Why else do we even bother making a society?
