Litova –
What makes her say that a working boy is not a serious learner? You can learn 60 minutes a day after work, and be more “serious” than the loafer who fakes his way thru a 6 hour day.
There are plenty of quality boys out there. Its her job / her parents job to find them. The biggest problem they face is overcoming the “what will the neighbors say” syndrome.
Take it from someone who was a “working boy”; we are fine bnei torah, and make terrific husbands / parents.
