Absolutely! ALL of them love the $$$ and the "celebrity status."
Speaking of Zach as one example, I can't think of any "calling", trade or profession that he would be equipped to pursue with the background, experience and training he has at this time. He has 2 children to support and ALL of the Roloff's (and offspring/partners) have become accustomed to a certain level of a "lifestyle" that the show affords them. Of course, there are the little sidelines and PR presence that they apparently thrive on, as well.
If the TLC cord was "cut" Amy and Matt would be fine financially but
