I fully realize that Detroit is a war zone with 90% unemployment, but do you really mean that in ten years' time an able-bodied individual couldn't find a couple of minimum wage jobs with less commuting?
With 10 hours of daily commuting at his current job:
$10.55 x 8 hours x 5 days x 50 weeks = $21,100 per year
With 2 hours of daily commuting, working a couple of minimum wage jobs:
$8.15 x 12 hours x 5 days x 50 weeks = $24,450
A 14 hour day instead of an 18 hour day, and he'd make more money. The full-time factory job probably pays some minimal benefits, so let's call it a financial wash. But 14 hrs vs. 18 is a no brainer.
Do you know why this whole story is so unusual? Not because of the man's work ethic and determination, but because very few rational human beings living in the US would do the same thing unless there was absolutely zero alternative for survival.
