Materialistic items are not liabilities. They are assets. Perhaps depreciating assets. Possibly poor assets to own as investments. However, nonetheless they are assets and not liabilities.

This is like Robert Kiyosaki's BS about your house being a liability. He invents new, counterfactual definitions for assets and liabilities and then proceeds to proclaim that your house is a liability.

That's like me redefining that wealth is having zero assets and lots of debt, and then using this BS definition to counterfactually assert that Jeff Bezos is one of the five poorest people in the world.
