Yea, not to say it's not the case. We're both trading anecdotes here. I'm sure there's probably statistics for it though.
My assumption would be that the amount to which someone travels is fairly correlated to their income, adjusted for local cost of living? I'm not sure where that would be higher though.
There's a big difference between in major cities and near major cities. Certainly, not all that long ago, wealthier people mostly lived in suburbs though that's probably not as generally true today for coastal cities in particular. I tend to know more older people who mostly don't live in urban cores.
