I'm starting to watch videos from today's China and comparing with 30 years ago its like night and day, sons have a much better life than their parents. The typical evolution from parents that worked on the fields to sons working with computers or selling things on Douyin. You see new cars, new buildings, from the outside you feel like this country is "going up".
Compare this to the USA now and 30 years ago. The disillusionment, the social strife, electing a president like Trump that makes George W. Bush seem like a good pick, people than can leaving the country for greener pastures... Sons have worse opportunities than their parents.
If you just compare the gradient of China and USA you will see it clear.
