Yes, independence is good. We don’t plan to kick him out the day after graduation, but a Plan is required, either for a position elsewhere, or full-time work here with a (short-term) timeline to have his own apartment and transportation. Since OldTax-lady is paying his tuition, he’s saving most of what he earns at Harris Teeter now.
Good for Bill, saving his money. That says a lot for him. And he will need it when he goes abroad.
When does he graduate?
