The young lad who blames capitalism has obviously never lived under socialism.
In an open market of ideas, critiques should always be welcome. Pigeonholing critiques of capitalism as automatic support for "socialism" is the opposite. Capitalism is basically a first step towards sanity, not some panacea.
For example, you go on to bemoan authoritarianism. But a corporation is an authoritarian structure, and your critique most certainly applies. The redeeming bits are that they're generally smaller scale than a country, and that there is often a higher level power structure that can moderate its worst incentives. But the same obtuse aloofness/politicking/groupthink do apply, as caricatured by the linked post.
