Edit: I ended up using this comment as an excuse to infodump but I tried not to do the
whole thing where, by infodumping, I am implying that this knowledge is uncommon or that the person I’m responding to is ignorant of it. And it appears that I’ve explained the idea of a leitmotif to a theater kid. My bad, Othello. I just like explaining things. Love your stuff 
it implied Hamilton is TOTALLY biracial
It’s pretty wild what facts needed to be left out or minimized to make this come across. Being playing by LMM instead of a white guy is a big part, obviously, but the whole idea that he was an “immigrant from the Caribbean” does a lot of heavy lifting there, too.
He was the grandson of wealthy merchants on one side and of Scottish nobility on the other. He was seen as lower status because he was born in the colonies and out of wedlock, but he was very much a colonizer. And his “immigration” was moving from one British colony to another and British colony. He received a decade of private education and tutoring before his mother died and it was that education that he used to be able to go to New York with the purpose of continuing his education.
you could have had a scene where sally hemmings comes out played by a child and had a long mournful monologue, about her abuse at the hands of jefferson, a "founding father"
For anyone who’s not super familiar with musical theater, it tends to make heavy use of callback, reprise, and theme to tie together disparate ideas. If you don’t know what that means, think of the happy music that plays in the beginning of Up. When that same music plays near the end of the opening sequence and that makes you wanna cry? It’s not just because it’s sad. It’s because the music juxtaposes the sadness of the moment with the happiness and hope they’d just lost. It’s that kind of thing.
Hamilton has stuff like this all over and is pretty tightly woven, but there are some dropped threads where you would expect some kind of callback and we just don’t get any. The reason? There were several more songs about opposition to slavery that were dropped because they didn’t play well in the test showings.
Hamilton is truly a story of oppression, as packaged for the privileged masses.
