London is the only city in the UK where that's the case, and many boroughs are commutable - it's only really the centre that's a problem.

A lot of tech industry jobs are also outside of big cities. (As are Google jobs in the Bay Area; the BA is just something of an outlier in that fairly conventional suburbia is still priced higher than just about anyplace else in the country.)

Dallas is pretty fine. For a few years, I lived within a 10-15 minute drive to my office on a $60k salary. Inner-ring suburb and not downtown, but most of the offices here are in the inner-ring suburbs.

(and if that sounds low, don't worry: I now make much more and work for a company that doesn't even have offices in my time zone)

It's probably completely do-able in the US except in the top 20 or so COL locations - https://www.numbeo.com/cost-of-living/region_rankings_curren...
