Why the war on merry-go rounds and rocker horses in city/school parks?

I’ve just returned to my city of birth. I’ve returned to the places I frequented as a child, and commented to my brother of how barren the parks seem.

He related his experience of taking his daughter to the parks, and how seesaws, merry-go-rounds, and even rocker horses were taken out of the parks gradually. He told me of how he and the wife found a seesaw in one apartment complex, and would take the daughter there – but then it was gone.

Those park toys gave me the best memories of playing in the park. If they are taking those toys away based on parents who are worried their kid will fall off and get scratched, that makes me mad. Why are they being taken out?

Why keep swingsets when they are more dangerous than those three combined?
