Would probably say I lean more towards higher pay than happiness. Even with a heavy work load you are still going to spend more time at home than work so might as well make high pay so your home life is comfortable. There are other benefits as well ... no stress for bills/ect. and the fact that if the pay is very very high you could probably retire much earlier with proper planning. Don't forget that accidents and misfortunes happen to all of us as well when you least expect it ... I had a situation like that a few years back, but financial security turned what would have been a devastating event into a minor inconvenience.
I am not sure what you mean by sacrificing morals ... like if you could become a hitman or sell weapons to terrorists? If that is what you are referring to then I would say no ... unsafe and even if it was safe I could never live with myself.
