Interesting, he doesn't portray his wealthiness in these readings, he seems to think kids might make him not have enough $ for books!

But apparently he needed to think about having to work for income to sustain a family.

I think he was saying working working like a neuter bee (as in just working without any kids of your own) won’t do. So the opposite interpretation. Everyone has to work after all, kids or no kids.

Another quote then:

"If marry — means limited, Feel duty to work for money."
