The ecological Cost of human Inequality

To make the discussion more relevant to this site, this claim surely breaks when it comes to entrepreneurs, who (when successful) create far more wealth for the rest of society than they gain individually.
I'd hazard a guess that they correlate reasonably well up to some point (most people making $150k have probably produced better stuff than most people making $50k, with exceptions on both sides), but get wildly erratic past some cutoff, where it becomes more an issue of connections with other businessmen and government, and the feedback loop of "you need money to make money". Is Carlos Slim the world's most valuable human, for example? Is Bill Gates the 2nd-most-valuable?
Off-Topic: Most stories about politics
If you look closely, most of the efforts against the "rich" are actually against those trying to become "rich", not the already very wealthy who have the politician power and otherwise many options (e.g. negotiate a tax treaty with a canton and move to Switzerland) to avoid such exactions. Throughout many decades of various economic conditions, tax policies, etc. how much was the wealth of the Kennedy family threatened?
E.g. look at taxes on earnings vs. principle. In the US we do have a big tax on the latter from the estate ("death") tax, although again the wealthy have options to mitigate that.
You will be hard pressed to find anything communist in that article.
That isn't to say that it's not unbalanced, but communism is hardly reason for that article.
*Private Wealth = "illth".
*Social/economic inequality is evil by definition.
*There should only exist "good jobs that nobody is ashamed to do".
*Having well defined national borders are evil.
*We should forcefully turn private property into public property.
*Owning your own car makes you a blight to humanity and the planet and
*we should all use public transportation instead.
I think you're right it's not Communism, it's a mental disorder.
