Indeed. It is easy to become romantic-nostalgic about unions, they fought to end sweatshop labour and in general for the moderation of capitalism. I think that a society without strong unions is doomed to regress back to the Gilded Age but I totally agree that unions have to adapt. I know nothing about it but I think there are academic folks who apply evolutionary logic onto human institutions so I'd say adapt is a good choice of words.
