>Almost everyone I know who travels to "see the world" lives in a major city, and almost everyone I know who lives in a smaller town hasn't even left the country in their lives.

And probably most of the people I know live in smaller towns outside of (many quite a way outside of) major cities or in/near smaller cities and many travel a great deal.

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.

I moved to a small town and I bought a lot of land because I am trying to become a YouTube and own a lot of machines and post lots of projects.

I can't get the land in city at affordable price.
