No. These aren’t measuring the same thing: the higher costs in the United States means that you cannot buy private plans which are as efficient as the national plans because you are also paying for the overhead of various providers and middlemen which only exist in one of these models, and you have limited ability to negotiate better prices or even visibility.

Software developers make somewhat more money but not enough so for this not to be a concern. If you’re getting hundreds of thousands of dollars more, of course, it’s a net win but if you’re not seeing such a stark difference it’s more debatable. If you’re not at the higher FAANG-tier level, costs for things like health and child care can close the gap considerably, especially if you or your family have less than perfect health and so the US option involves an unpaid second job haggling with insurance companies about coverage.
