She is right. Here’s why:
By the time she is dating, she has more than likely begun working, and is most likely well on her way to a promising carrear, which will provide a decent income. He has most likely not done any of the above.
She / her parents need to beg and plead with a shadchan to get noticed. He just needs to have a pulse and not drool when eating.
She will juggle the responsiblilty of working AND running the house / kids. He will expect a thank you if he puts his clothes in the hamper.
Shall I keep going?
