In China, between 1958 and 1962, there was a big plan called the Great Leap Forward. The leader of China, Mao Zedong, wanted to change the country from a farming place to a modern place with industries and factories. Mao thought that if people worked together on big farms and made lots of grain and also made things in factories in the countryside, the country would be stronger. People who worked for the government tried very hard to do what Mao wanted because they were afraid. They told lies about how much food they had and took too much food from the farmers, which made many people very hungry. A lot of people died because there was not enough food. Some people think that 15 million died, and some think even 55 million died. Mao also said that everyone had to farm together and no one could have their own small farm. If people tried to keep their own farm, they were treated very badly and called enemies. Everyone had to work very hard, sometimes in ways that were not very useful, and the big changes they were trying to make did not work well. Making things in the countryside did not go well because the plan was not good. The Great Leap Forward was so bad that it made China's money and work worth less, and it was one of the worst times for China's economy. An expert named Dwight Perkins said that even though the government spent a lot of money, they didn't make much more food or things, and it was all a big waste. After a while, Mao let other leaders who had good, practical ideas take over the day-to-day running of the country because the plan was not working.

People who are part of the autism rights movement think about autism differently. They don't see it as a bad disease that needs to be cured. Instead, they see it as a different way some brains work, and that's okay. They want everyone to understand and accept people with autism just as they are. These people don't want services that try to make them look like everyone else; they want help that makes their lives better while letting them be themselves. The people in this movement think that being autistic is a natural thing and that it should be respected. They believe society should make it easier for autistic people to live their lives, not try to change them. This idea is different from others who think autism is a mistake in someone's genes or think it comes from things like vaccines, which is not true. The movement started gaining attention in the 1980s and 1990s. A man named Jim Sinclair was one of the first to say that autism shouldn't be cured. He started groups and wrote things that shared this idea with others. Some people agree with the autism rights movement, but not everyone. Some say that the movement is mostly led by people with autism who can speak and write well, so they might not understand the challenges faced by people with autism who also have a hard time learning things. These critics worry that the movement doesn't speak for all autistic people or their families.
