We have neighbours from the US (renting, she is doing a Masters degree here) and their son just applied to be a Chicago cop.
My neighbour said even he was a bit surprised at just how good the money was.
I suppose there are other things to consider in the USA though, top line cash is fantastic, and if you have health care it feels golden when you are working.
But health care once you retire? No sure how that works, I do know that pay as you go is prohibitively expensive.
Also (again, the neighbours chat) the cost of University Education if you have kids is stratospheric, thats why there are so many yanks here (and in Glasgow where my son is studying) and happy to pay for it.
