I think it's because many kids today are 3rd generation Dubs, so they have seen the BOrg's effect on their parents' and grandparents' life decisions. Decisions not to pursue a career, to make pioneering their career, not saving for the future, not buying houses but renting instead, expectations of Armageddon coming "any time now" etc etc.
These things have made an impact on later generations observing how the Borg has impacted their family. And seeing that many of the Borg's "suggestions" have been to the detriment of people, younger ones are wising up and deciding to do things that suit themselves first, rather than allow the Borg to dictate how to live their lives.
I was a 3rd generation Dub myself, with many relatives who are/were Dubs too, so I've been able to see things for myself. I was brought up during the "no tertiary education" period, so I never got a university degree nor persued a career. Neither did my sister who is 12 years older. My sister got married during the "no kids in the last days" phase during the late 80s. She put off having kids until it was almost too late for her to bear them. She also regrets not going to university. So guess what? Both my sister and I are determined that my niece will be allowed to go to university if she wants to, regardless of what the Borg says in 10 years' time.
It's our life, and the Borg has no right to dictate how we (millions of people) should live their life. What right do they have?
