I grew up in the South. You'll have to kill these people to take away their sweet tea and fried chicken. And that's just one dimension.

I live in the countryside. In 2018 our small neighboring town of about 13k residents had their first murder since 1965, and none since. That works out to about 0.12 homicides per 100,000 residents annually. By comparison, Baltimore has 22 per 100,000 annually.
The murder thing is also an error of faulty generalization. As a counter example, Opelousas, Louisiana, a nothing town with barely more people than yours, has a murder rate of 39/100k, higher than your example of Baltimore, and much higher than New York (3.92/100k).
When I run the calculations and take vacation, health, education for the median person they are close to similar.
But these calculations does not take into consideration: less noisy cities, walkable neighborhoods, longer life expectancy, higher quality food, better workers protections, education, etc.
An honest study would need to include the value of the commons.
> roughly 20-40% richer
This is likely wrong. Americans have better purchasing power, but are not necessarily richer.
