The money doesn't enter the question for Jack and Lureen as far as we know, except that she controls it. For Alma it is a problem, since she has two children to look after, but Monroe and Ennis's payments solve that problem.
I don't know, and I don't know whether Jack wouild know, what he's get if he divorced Lureen - I bet they had no community property thing in Texas then - but if Ennis had asked him to come he'd have dropped Lureen and the business and gone straight to him, regardless of the financial implications, I think.
