The article touches on a lot of issues but one I find interesting is: why does it matter?

It provides the following answers, which seem weak to me:

  1. "[historian and economics professor at Harvard]: 'I worry they’ll come to severely regret their choice if they realize the best jobs require a degree they never got.'"
  2. "...further delays in marriage and childbirth may ensue. That would further reduce U.S. fertility rates, which worries some commentators, albeit not all."
  3. "The most severe implications, I suspect, will be cultural and political. The U.S. electorate is already polarized .... Those divisions seem likely to worsen"

I'm not sure this is convincing. It seems to boil down to a historian worrying, fertility rate changes that some people may view badly, and a possibility of increased political polarization... meh?
