I appreciate the link, but there's nothing in there anywhere about how it differentiates from Reagan's outside of him pointing out that it is different and that even if it weren't Reagan never trademarked it. He's having a conversation about trademarks, not about what it means. He did say that he put "Again" on the end of it because without you're implying that America's not great, but he doesn't say anything at all in that interview about personal agency versus the collective. In fact, I'd say he does quite the opposite almost every time he talks about it when he says "We're gonna Make America Great Again."

You can interpret it how you want, I guess, but I don't hear collectivism in that, I just hear a common goal.
