This just isn't true. The majority of the US has cheap housing. The person who wrote the article lives in Pheonix where you can get houses for 200k or under. Like this perfectly good 3 bed 2 br for 200k:

Housing costs are out of control in a handful of places in the US. In the rest of them it's as cheap as ever. Or even cheaper given the very low interest rates.
It can be stupid cheap to live in the US. Rent a room for $4-500, buy a late model Toyota for $5k, and eat like a poor person. It's pretty easy to accumulate enough money to break the cycle of poverty.
The big pitfall is health. If you're sick then yeah you're pretty screwed. But outside of that as long as you avoid unplanned kids, jail, and drugs it's pretty smooth sailing
