Here’s my take:
If there is a criticism, it is on the parents, not the guy. A guy who wants to learn, needs to either stay single, get his parents to agree to support him, or marry someone who can support him. Presuming we are talking where the guys parents don’t want to support, his only choice to get married is to find someone who will support him.
As far as the parents, I still think the criticism is better, but still not as bad as it seems.
There is a presumption that the girls parents are more responsible for support. I would imagine that stems from the notion that support is instead of the wife working.
However, the wife working really is not enough income for real long term learning, and there really is no logical reason for the burden to fall on one side over the other.
Bottom line: Don’t like it, marry a working guy.
