Good luck with rising Birth Defects
Career first, thinking they can't afford kids...very bad decision...they are not thinking right. Having kids late is a very bad decision, IMO, we have seen/experience this in our own family. The kids will be graduating while the parents are in the 60s/70s. Most won't ever experience grandkids. Their energy level is no where near that of parents in their 20s. You can see the older parents are wore out, big time.
Only plus side is it keeps the older parents moving and active.
Had an Aunt at mid 40s have a child that did not make it, never developed correctly, skull never came together along with other issues, child was never born. So what did she do, got pregnant again closer to 50

Well sure enough their son is very slow, had to go to special classes, is having a hard time getting a good job. Only good thing is he is not on any gov't assistance. He talks slow, thinks slow but no different than a real old person, IMO. He has to work two jobs to be able to live normally, mainly because the type of jobs he gets don't pay much. Will say I love my young cousin, he is one of the most happy people I know, great personality, don't let problems/issues get him down, never seen get him mad/angry.
