This is a GREAT point, but hard to do in practice when deferred can be several multiples of base. I know many people who internalize large sign on bonuses and deferred comp as though they already earned the income. They are psychologically unable to accept writing this amount of money off, and force themselves to stick in situations that are at times not healthy or at least sub-optimal. Often times this is called life, and you deal with it because it is putting food on the table and providing above and beyond for your family. However a lot of times it would be better to just find something that makes you happier which is easier if you don't factor in deferred comp when thinking through personal finances.
