Except that in the 19th century you have millions of people in the United States living in Slavery, Women could not vote, and Business often used little children for labor.
Not sure I see the major problem there...
I’m against racially-based slavery but not the practice itself.
I don’t believe women should have any political power. Especially not the vote.
Many children do not have the intellectual power for higher education, and would benefit from apprenticeship and technical/professional training instead of high school.
