That may be true for some physical objects, but not for things like a secure retirement, protection from crippling health-care bills, and secure (non-bank-owned, non-landlord-owned) housing. There are vast and real inequalities there.

[fvdessen]

All those inequalities you cite are paradoxically the consequence of the vast increase of wealth and services accessible to everyone.

The retirement insecurity is a consequence to lifetime expectancy having increased vastly beyond retirement age. The health care bills ? You couldn't even get them before, as all the healthcare one could expect was penicillin, aspirine, bandages and hot soup. Housing ? People would live with their parents until and even after they married. Now people can afford to move out and divorce.

Social behaviour and expectations have changed to fill in the opportunities offered by newfound wealth, driven by the search for longer life and higher social status.
