Well, I don't think so, since I lived in multiple cities, the order is totally messed up.

Also for e.g. in Amman, public transportation, might cost 0.40 JD, but they don't get anywhere, and in most of times, walking is much faster that taking the bus.

Also there is no such thing as unlimited data plans there too.

So at least for the middle east, I don't think it's accurate.

It doesn't seem very accurate in Munich, either, particularly WRT housing — all the 1BR flats we saw were north of 1,200€/mo.
