Patriarchy in all decisions. The old men make choices for families based on what they know is best, and you follow that rule, regardless of your own views. Women are not allowed a voice in formal decisions. Children are a tradable commodity. If you upset an elder, your life is over.
You're raised speaking German first, so that you can "learn your heritage" (read: always feel the divide between yourself and the rest of the country). You get up to an 8th grade education and nothing more. Only if it doesn't interfere with your chores. If you are sent off to college for whatever reason (my neighbor was a college educated Amish; he was the legal representative for the community) they treat you like an outsider. You are not allowed a voice in community votes, if they have them. You get the scraps. If you start a business, and someone else wants to start the same thing, you give it over to them, no questions asked.
God forbid you disagree with the elders. Imagine being in your 30's, with just an 8th grade education, and your entire community, family, and support system turns their back on you and yours. You're screwed.
If the bishop believes another community could use your skills, or doesn't like your family, you have to move, possibly hundreds of miles. That's after selling everything you own, usually at a loss. But that doesn't matter, because the community itself and the church actually own everything, you are just renting your own business and/or home from the church.
Absolute rule by the male elders. Lies and buried secrets. That's the way of the Amish. But they get a pass, because their beards and hats look funny.
