Those who move to cities and can live without cars have far higher incomes than median, and because they are not burning the average of $700/month on a car, they accumulate wealth far faster.
If I have misunderstood your assumption, please correct me, but the "only poor people don't have cars" fallacy is the only way I can make sense of your comment, and the only people I have heard express it are deeply out of touch with the modern world.
There are a FEW things that decline with greater wealth, like number of children, that buck intuition, but it’s not super clear what the cause and effect is. Suffice it to say, if what you were saying is true, which is improbable - I’m not saying impossible, just really improbable - we would be talking about it way more.
Now why you have to go and call me out of touch and all these big harrowing names, I don’t know. I’m just trying to talk about what is likely to be occurring. People make less money and cars are more expensive so fewer people own cars: that shouldn’t be a controversial POV.
