Not viable for certain locales in the US. Its far more affordable for me to live 50 miles away from DC metro and commute 100 miles a day than to live in closer with my family of five. Its not just housing that gets more expensive as you get closer to metro areas, but all of the associated things that go with it as well (groceries etc). I could work in my home town, but then I couldn't afford my home :) Pay drops about $30k over 50 miles. I'll take farmland, clear streams, beautiful views over city living any time.
