I think this guy is missing the point entirely.
Capitalism doesn’t produce inherent ugliness, but such ugliness is undeniably a symptom of the greater capitalist disease.
Wal-Mart and stores of its ilk are ugly. Regardless of the efficiency and functionality of such institutions they are – in an external aesthetic sense – eyesores.
On the other hand, places like Grafton Street or, say, Fifth Avenue – grand temples of, and monuments to, capitalism – can be quite beautiful.
In the right light, of course.
