I'm in this (job) right now because I make a pretty good income so if the opportunity presented itself that provided a better means of financial support, you bet I'd quit.
I didn't get into this profession because it was my "calling" or life's passion....so getting out for the same reasons I currently stay seems a like a no brainer for me.
^ that.
It would not be a 'raise', it would have to be 'set for life' money. Millions, honestly. If I could pay off all debt, set aside trusts for my kids, live until I was 101 without a worry about money, sure.
Otherwise, I'm working. A raise/any job can be lost.
