 Well, thanks very much. I have a question for Marianne. You know, Bennett of the UFT alluded to, quote, entrenched powers. I think I know who that is. I'd like to ask Marianne if she'd like to talk about that. And for 40 years, we've had Tier 1, Tier 2, Tier 5 retirement. I was in a Teamster local with A and B workers. This is nothing new.
