There are lots of stories nowadays about young people being scared shitless of having kids and there's one way to be sure that doesn't happen. That could be a factor, too. Particularly for those for whom college is barely affordable. That expense makes it difficult to go out much at all, nevermind dates. TV and culture hasn't changed that much for gen z, which still says that you have to spend money/have a car/live on your own to be worthy of dating.
