If we're going to talk about ageism let's talk about the fact that it is still perfectly legal for older people to discriminate against younger people, and until that changes, any complaints about this topic (from people who generally hold the majority of power/wealth in this country) frankly sounds really disingenuous to me.
I'm aware ageism is a problem, but I'm not sure we should be feeling overly sorry for executives that make far too much more than the (much younger) people below them.
