Perks have gotten better in some dimensions - for example, parental leave is much more generous than it was even 5 years ago. And that’s probably a more important perk than free backpacks tbh.
Important or motivating? It is not the same thing. For older people that already have kids, parental leave is useless.
How many times in your career will you use that perk?
Depends what profile you are trying to invest in.
I'd be interested in utilization. When I was there and had my kids, it was 12 weeks, and I never took the full 12 weeks because it was too long for me. (I took 6, the 7, then 4-5 IIRC.)
