Look at it this way: conspicuous displays of wealth are very cheap signals for the rational members of the human race to pick out what we call, in technical sociological language, "wankers".

Indeed, nice cars say to me: "there's a moron who lacks taste/perspective, and probably is really bad at managing their life and money. They probably have large amounts of debt and leverage.".

You can call me judgmental, but its an infinitely better attitude to take than anything approaching admiration/jealousy.
