Yep, given sufficient externalities, this is true. As an example, watch this fictional response to the fact that better cars cost more: Let's get the poors out of safe cars. The peasant class belongs in beaters, while the rich ride safe. Consider the choices necessary to make that statement untrue.
You mean how the richer you are, the bigger (and safer) the vehicle you can afford? I drive by many parents taking their kids wherever in old corollas or kias or other small car, and I see many parents at my kids’ daycare dropping their kids off in large suburbans/F150/Sequoia/etc.
An argument that rests on equality should support the idea that all people deserve the same car irrespective of how much money they have.
