That principle even applies to progressive types too. Some examples:
- People demand that their own kids go to school every day and learn things.
- People demand that their kids work and become independent
- People force themselves to conserve assets and not to be reckless
- People do not welcome strangers into their homes
- People demand that their families be law-abiding and respectful
- People demand perfect behavior, appropriate dress, and positive achievements of their kids
I guess I could go on and on, but it's interesting how our conservative, bourgeois expectations can dissipate the further people are from us.
