oomis: The Yeshivish shidduch system is much closer to the Chasidish shidduch system (as different as they may be) than to the MO dating system, that you oh so strongly advocate, if you must do a comparison between the three.
And both the Chasidish couples and the yeshivish couples most certainly are ready for marriage. It is the MO couples who are long overdue and way past the time they should have gotten married, by time they do.
