I think the above words were meant to be a celebration of the fact that so many of us actually survived our childhood despite the problems, hazards and downright dangers that we experienced on an almost daily basis.
Yes we did some quite ridiculous and dangerous things, but would any of us say we wish we had been born In a different time. I think the answer is not only no, but hell no.
I have no doubt that our grandparents would say that they're childhood was better than ours, and probably kids born after us will say that they're childhood was better. It was what it was, no better or worse and anyone elses childhood, but we look back fondly at what we did. And why shouldn't we. ?
