Maybe its just because I live in a middle class suburb of Kansas City in the “bible belt” but I see plenty of people who do want a traditional marriage and family. Most people own cars designed around children. When developments are built they have playgrounds and pools. People buy a home based on the quality of the schools.
I think alot of us go thru a stage where we enjoy our young and carefree days in our early 20’s when we live in an apartment have do the bar and club stuff and have several relationships. But somewhere past around age 27 we decide we want to start settling down and looking for something permanent.
