Joseph,
Hello, there are plenty of Litvish boys but too many of them are totally incompatible with the girls since they have zero accomplishments in learning, education, work, life choices, etc. If your “common sense” was spot on, these shidduchim would be happening in droves and there would be no need for this post. Girls aren’t desperate enough to abandon their legitimate need for compatibility to marry chassidish any more than they are to marry some total loser.
