> The last century has been painful for children as every venue of leadership has been used for abuse...
I'm going to preface this with "I have no hard data to back this up", but I have a feeling that this isn't a matter of the last century as being more of a problem than previous ones. Rather, I think it's the globalization of communication that has brought it to light in that time. This sort of thing has probably been going on since there have been positions of power (pretty much forever) but in the last century it's become much more easy to report on cases when they're found. And now thanks to the internet, with the ease of communication between people that you may never meet in person otherwise, corroborating stories and figuring out that there's a problem is an easier process.
It does a lot to highlight the dumpster fire that is the terrible side of the human race, and many positions of power are still powerful enough to evade consequences too much of the time, but maybe one day it will give voice enough to the oppressed and abused to be able to start making a real difference. (Not that it should be _solely_ their responsibility, but in order for the process to start, they have to be able to speak and be heard.)
