Things certainly have changed.
When I was 4 years old I'd just tell my parents that I was going out to ride my bike or go to the playground and they wouldn't worry nor did they have reason to.
When I was seven my mom would give me 15 cents and bus tickets and I'd go downtown by myself to go to the "Good Deed Radio Club". My folks didn't worry nor did they have reason to. (Can you imagine having something called the Good Deed Club now?)
My mom walked me to school on my first day of grade one and never again. No reason to worry.
Kids are far more sophisticated today but they aren't any more mature. I personally don't think that's a good combination.
Sure some things have improved in some ways. Our standard of living has gone up for one thing, women have more options, but on average I have no doubt that our quality of life has gone down.
Everybody is entitled to my opinion.
