I like the movie a lot, but the beginning is a little problematic from a modern viewing iirc. It discusses how the poor and uneducated produce more kids than the higher classes, thus a dumb population after many generations.

Factually true about the correlation between higher standard of living and having fewer kids. However, that exact discussion has been used as a dog whistle against other "undesirable" groups in the past. The movie's beginning implies it would be better if we decide who gets to have kids.

Overall a great movie, but I think that part has aged poorly.
