My observation is that it is clear evidence of our wealth, and ability to cater to extravagances, that people can afford to buy and maintain vehicles, and entire artificial lifestyles, that are valued primarily as symbols. Instead of as simple functional tools for getting a practical and necessary job done.
For some reason this reminded me of where I've read most millionaires live in modest homes, drive later model vehicles, and live rather unassuming lifestyles. From what I've seen, more often than not, its those who can least afford the lifestyle who pretend to have wealth.
