I'm not sure why we're doing states vs cities. Jackson (the largest city in Mississippi) has a population of 150k. If I find a non-commuter belt town in the UK with a size of 150k, then the house prices will be dramatically lower. An analysis of London house prices needs to take into account that major urban areas in general command a premium (for reasons other than the ability to earn more).
If you compare SF or LA to London, then you'll find:
City | Median Wage | Median House Price | Ratio
SF | 104k | $1.5m | 14.42
London | 67k | $890k | 13.28
LA | 73k | $1.1m | 15.07
London ends up being slightly more affordable despite lower salaries.
The whole analogy was a bit meaningless - it wasn't an apples to apples comparison. The writer mixed geographic and demographic scales to make a point that could just as well be about the unaffordability of large cities.
