I'd be interested in hearing from some US-based contractors who feel the same. The thing that has stopped me going down that road is the insane health insurance costs here.
Yeah, contracting is very tough if you're responsible for a familiy's welfare. I did it for a few years, 2008 - 2011. But back then HSAs were quite reasonable. With a wife in kids I can only imagine what premiums are now days. However, when the kids leave I'll seriously consider going back to contracting.
One other thing I found out was to stay away from the "butts in seats" contract. That's often the model these contracting houses (middlemen) use so, in essence, you're the same as an employee with non of the benefits. It can still be good to go through one of these companies but make sure and tell them that if you're work is blocked because the customer is dragging their feet on requirements or the like, you reserve the right to work on other contracts. Don't let them bill you out at 40h per week if there's not 40h per week of work.
I'm in the fortunate situation of having a wife whose traditional employment includes good health care benefits for the family, leaving me free to focus on cash.
