How is “the burning need for many young girls (let’s say ages 19 – 23) to get married” a crisis, or how does it lead to large groups of unmarried singles? If they didn’t want to get married, lichorah there would be more.
The cynic is the one who defines kollel as a group of batlanim in it for the easy life. There are some (who are idiots because long term it’s harder), but it’s a minority and in no way defines kollel.
