Does US society really worry when men and women don't get married and have kids?

Hi all! I've been reading about how more and more American men and women aren't tying the knot anymore. I'm 29 years and I've never been married. I have absolute no intention to get married or have kids either. However, many unmarried people are still, of course, having and therefore, more and more babies are being conceived and born into the world to unmarried parents. Does US society really worry when men and women don't get married and have kids? I mean, is this society's worst nightmare? Hypothetically speaking, if people stopped getting married all of a sudden, would that really impact our US society with dire consequences? Many people in almost all societies around the world, not just here in the US, say that marriage is the fundamental backbone for a country to survive in the short-term and in the long-term. Any answers would be appreciated. Thanks!
