Could extend that train of thought to expensive cars, expensive houses, cellphones, clothes, etc.

We could all "get by" living in 10 x 10 apartments with $5000 Smart Cars, basic brick cellular telephones and potato sacks for clothes.

Does the guy who owns a Lamborghini but has no idea how to maintain it really deserve to own that car?

If it makes you feel better, consider that every person who buys a $4000 road bike made by the same company that made your bike in part help that company sell you your bike for just a little less than otherwise.

If nobody bought Lamborghinis, and let's face it, nobody really NEEDS a Lamborghini, the company would cease to exist.
