Joseph:
I know that (and have quoted it many times). It doesn’t hurt to try to find the few that are not interested in being supported 🙂
But seriously, how many of us (even now) could have supported a son-in-law like the TAZ (who insisted in the dowery that he be served meat every night, as that is what he needed to learn, and won a Din Torah when his shver (The Bach) wanted to serve him chicken (or lung) instead !!) (A rayah against CherryBim on both accounts)
tzippi: Not nogayah, as they would not have gotten in. The however many (don’t know exact number) that did get in (after knowing Nashim Nezikin Baal Peh) would rate, but almost all would go into rabbonus after a few years (as was the norm in Europe).
