They have cars, and a place of shelter that they own. They have family. I scrape by paying rent and put food on the plate, and ride a bicycle to work every day. I still can't afford to learn to drive. Parents won't support me, although I spend 3 months of savings to buy a plane ticket to see them each year, using the 8 days of holiday I'm offered. Most of my friends and colleagues earn half of what I do. The idea that someone could earn 30,000 USD in Alaska in only a few months sounds unbelievable to me. The trailer lifestyle would be an upgrade from working for a tech company in Asia.
