Donald Trump summed it up in a nutshell in the Access Hollywood video - if you're famous, they let you do it. Or, to turn that on its side, if you're famous, people are less likely to believe your accusers, at least until relatively recently. #MeToo has cast a light on some of this.

I have a distinct and disturbing memory of a girl about my age who I think was probably molested - her suggestions seemed crazy at the time, now I realize they were a cry for help. But I was 9 or 10 and didn't understand and didn't say anything to my parents. I went home and never even walked past her house again if I could help it.
