so much to say , a short answer on erev shabbos is
1. everyone is free to choose who to marry and deal with the consequences
2. the reason why “working boy ” is a chisaron for most is simple, and that is a kal vechomer .. if the yeshiva bochur is not much to write home about and barely a chatzi guf … what do u want from the bochur who didnt have sipuk in learning and at a young age worked in a warehouse with mexicans or worse in a office w secretaries…
3.. ayyy some working boys ARE kovea itim & maybe even had an aliya from working & being on a schedule and… the teretz is those few exceptions have plenty of names and many girls would grab that if it really existed
much more to say i know the above comment is logical & lacks sympathy but will be mamshich with feelings mayb motzei
