The macro economic and political landscape does not support having children. I would be very interested in seeing if there were any substantial disparities across racial and class lines. My Black peers/family/friends all aspire to have children at some point or already have kids, it doesn't matter if they are white collar, blue collar, or poor. Whereas with my white friends who are mostly white collar, it is a mixed bag.
A very good book to check out regarding the different attitudes regarding long term goals across class lines is Joan C. Williams's "The White Working Class". In it she points out that the professional managerial class emphasizes self-actualization as one of the the primary goals in life, and having children doesn't necessarily sync up with that and may actually undermine that goal. Whereas blue collar people tend to care more about legacy and the maintenance of traditions.
I personally don't want to have kids and I'm an outlier amongst my family, my folks look at me like I'm crazy. A part of it is not having the innate desire to have children, and then looking at the financial costs of what I would probably have to spend to raise my kids and put them in a position to surpass me academically/financially. Films like
American Promise and
Class Divide showcase how difficult it is to compete in a major city against these yuppies.
