Individuals not having a support-structure in place to help them take care of kids (i.e. family) is both a symptom and a cause of individuals having children that they can not take care of. If they struggle to take care of their children, then they'll probably struggle to help their children take care of their own children.
I'd posit that this is endemic to our "credit/loan" society, where everyone feels the need to have things that they can't (yet) afford. If they just hold off on their self-indulgence for one generation (or x-amount of years) until they can afford to have that item, then they will improve the lifestyle of their following generations by an unmeasurable amount.
For most people who struggle to afford their kids, its not other indulgences that cause it. There is a whole section of society who work hard but can't get by.
