It's not totally clearcut is it. Personally, it's important to me to have a rewarding and enjoyable job, and to have enough money to support my family and taste in expensive toys. Would I take a less interesting job for more money? - probably not. Would I take a drop in pay for a more interesting job, yes if the pay didn't drop too much.
Can I find a more interesting job that also pays better, well I keep looking.
