I think one need to understand that those kind of things have been said about western capitalism/society for a long long time, even under appalling injustice, segregation etc. Its purpose is to comfort the privileged, not necessarily to be true.
The underlying pattern has been there for even longer of course, e.g. Bertrand Russell wrote this in 1932:
In the past, there was a small leisure class and a larger working class. The leisure class enjoyed advantages for which there was no basis in social justice; this necessarily made it oppressive, limited its sympathies, and caused it to invent theories by which to justify its privileges.
