Well at some point it doesn't matter if it's worth it. Going from lots of money to not much is a recipe for divorce. Of course if you're divorced for any reason, the judge will impute your income at what he thinks you can make. So you'll be paying child support and alimony based on the "job is shit" high rate job and utterly fucked if you don't work it. You better be damned sure you're willing to work the "job is shit" job forever once you take it; the judge will make sure of that.

According to my state AG website, after Loss of employment/change in job income the paying spouse can request for review of spousal support.

(I don't have the stats for how often it is granted)
