That's a cool stereotype to talk about, but for every broke guy that makes $200k living in Wyoming, I know more that own 10 acres, a nice house, a 3000 sq ft metal building next to it, $10k+ in guns and ammo, several paid off older vehicles, and one nice one with a payment for the wife and maybe himself. That is much more common that someone that makes great money but just CANT curb his spending.
I didn't work with any offshore people. I knew a directional driller very well and visited him several times, and from there met a few welders as well while we worked on helping them install off-road suspensions onto their trucks. All had nice houses and sounded like they didn't have a care in the world. Very different from my silicon valley friends complaining about their high rent and housing costs.
Most guys I know had their housing provided on site. They then traveled home between jobs. Or others had RV trailers with them so they didn't have to go home, if they even had a home at that time.
