BlackIntrospection Speaks to the common fallacy of pro-capitalist arguments.

As an advocate of social democracy, participatory economics, another point that the article didn't bring up is that the failure of other systems, communism, socialism didn't occur in a vacuum. Capitalistic economies have long been at war, with guns and dollars, with the economies of socialist societies. Exactly(!), one might say. And the better system won.
No. The article made a point about economics being a 'behavioral science'. Yes Yes Yes
Solidarity and cooperation are core values of socialist/communist models while unrestrained competition fueled by greed is the central component of capitalism making it more suited to destroy other economies but ill-suited to build societies sustainable to natural life (human, plant or animal).

The merit or detriment of capitalism shouldn't be viewed through the lens of competition with other economic models. It will destroy them, no doubt. Today's problem is that in a society dominated by capitalist thought, that destruction is conveniently interpreted as democratic expression of basic human values when it actually is the demonstration of a historic instance where the promotion of one human value, greed was done more successfully than another human value, cooperation.
