I think Jeremy is doing exactly what MacArthur & Company wants him to do, and he's on the path to get where he wants to go. Wherever that is. There's nothing either one of the Vuolos do or say that's contrary to that. No career angst, unlike Deertick and his revolving "callings".
As for gaps between Jer's abilities and his goals, I haven't actually seen what his goals ultimately are, though I may have missed that somewhere. Thus, I don't see the gaps.
I don't know or care where their money comes from, but they seem to have sufficient. I don't know or care about their contract with TLC, but they seem secure. I don't know or care about their next home, but they don't seem concerned. They eat well, dress well, socialize with a diverse group of friends, have a adorable happy toddler and appear very devoted to each other.
Nope, don't see any worry, discontent or confusion. YMMV
