To be honest based on my experience I don't think that's the norm.
Most of the OFW's I knew in the UK were living in little Filipino 'communes'.
Sharing living space and costs and send the largest part of their income back home to families, spouses and children.
It was the pretty much the same story in Japan. Although many were TNT
Plenty of our 'friends' in California also in the same boat.
OFW's making lots of money are few and far between. Although they do exist but oddly don't consider themselves true OFW's just ex-pat workers....go figure
