As someone who found her spouse on a dating app, personally knows at least three other married couples who met on dating apps, and is fairly sure I wouldn’t have met an acceptable partner without the use of that technology, I really don’t think one of the problems is more choice in partners. It’s definitely short-term thinking and related values.

Dating sites, by allowing me to find out quickly who had those incompatible values and weed them out before wasting time on them, while connecting me with a compatible person I never would have met otherwise, directly led to my marriage and child.

I think pushing college, student debt and focusing on career above all else (especially for women) is more of a causal factor than dating apps. Too many get sucked into career to even think of committed relationships or being a mom.

I think the fact that "older" women having more kids than younger bears this out as well. The 35+ women are considered "geriatric pregnancies" and come with increased risk to both mother and baby, and the fertility window is closing. These women are old enough to have "been there done that" with corporate life and are more likely to realize their time to start a family is limited.
