I went to Manual Arts High is Los Angeles in the 80’s. It was overwhelmingly black back then. Now, it’s overwhelmingly Hispanic. This happens everywhere. Immigration (legal and illegal) is changing the face of most big cities in America.
My grandfather went to Manual Arts in the 1930’s, and I believe it was mostly white/Jewish then.
My Father graduated from there in the 1940’s. It was all White back then. He loved the school.
