Maybe some did, but not my Gen X wife or I.
We raised our daughters to be kind, but tough, playing outside, riding horses and pedal bikes all over, they had daily chores, and minimal screen time.
Now that I am raising my 6 year old, same thing.
She is home schooled, and rarely in the house from 7am till 5pm unless doing school work.
The rear tire blew on her pedal bike, when i looked it blew because it was completely worn out, which is a good thing, it means she rides it a lot.
She has chores to do every day, and never complains about them.
Last week while in town one day i had a chiropractor appointment. While sitting in the waiting room I gave her my phone to play with, and that was the grand total of her computer/phone/tablet time for the week, except for a 5 minute phone call she got on my phone, from her grandparents on her dads side, and a 2 minute call she made from my phone to her friend, inviting her friend to the pool with us when we went.
