Lmao Frankfurt is not to Germany what the Bay area is to Cali. The Bay Area is so ridiculously overpriced it tops the worldwide charts.
Comparing at a country/state level, Louisiana-Cali is a 1.5x difference while Romania-Germany is a 2.7x difference in nominal GDP per capita... and it was way worse right after the fall of communism. Like, "oh shit oh fuck why are there so many orphanages and so many homeless orphans" kind of worse.
