Not necessarily, because other locations that have lower cost of living may also have services lacking like average bandwidth, electricity outage rate, food security, political instability, etc.~ can't ignore the hidden costs.
Those hidden costs are part of the cost of living, no?
Just in the US, though, I think it's hard to argue that a person making $200k/yr in New York City is meaningfully making more than a person making $50k/yr South Bend, Indiana.
