Thanks for all the effort you put into this @livinguktaiwan! So interesting to see these results.
As I suspected, we're pretty screwed, living in one of the most expensive parts of the USA. In retrospect, I would like to add — as a bit of extra perspective — that Washington state also has the highest minimum wage in the USA at US $16.66/hr, compared to (for example) Texas, which still follows the Federal minimum wage of US $7.25/hr.
Relatively speaking, though we still can't really afford our lives, mostly thanks to insanely high rents, as a result of insanely high property prices.
Your input to the index was certainly an eye opener to many of us especially outside the USA, and it was also good to have another data point from Texas to show price parity within the country. Thanks so much for providing such a comprehensive insight and all the work you did in the conversions
