Summary - Detroit/Michigan wages are three to five times higher than all of the above EU/EEA countries.
No figures are PPP adjusted (but clearly there is a very large gap between Detroit/Austrian-grocery-store-wages compared to much of the EU/EEA).
If we don't want to stick to the EU (btw, you originally referred to "Europe"), using the examples proffered so far:
Mexico 664 EUR per month vs Ukraine 264 EUR per month
Mexico and Ukraine I cannot comment because I know little about it.
