Since in America we no longer need kids to till our fields, pick rags or otherwise make a living, there's no economic incentive to having kids. So if you have a kid by choice, you probably feel at least optimistic enough that you'll be able to raise your kid under a roof. But if you're always hearing that your generation is worse off than your parents and grandparents (in some way), that has to discourage a lot of people from having kids, and so there's less incentive to marry. Not zero incentive, but, one incentive has been weakened. And then, if you actually are worse off than your parents, evidence being that you're living with your parents, that has to also discourage yourself from wanting to marry (can't afford to move out, don't want to honeymoon under my Star Wars poster) or discourage someone else from marrying you (don't want to honeymoon under their Star Wars poster).
