There are differences, but this is oversimplified, and market is “mostly” working. You need more money in California, for transportation, for health care. The standard is bigger houses (bigger everything) in Cali. Life might be richer, in some ways more pleasant, in London (it’s not weather though), including shorter flights to many interesting places.

From my experience the ratio of savings was similar, but the ppp of course favored US for absolute numbers.
