Many crazy ideas are popular until they’re proven wrong. People once believed the earth is flat. They believed you’d fall off the edge of the world if you went too far. The sun revolved around the earth, of course. And there were dangerous dragons waiting in far-off lands to greet anyone who dared to go there.
People eventually realized that all of these notions were wrong. Sailors proved that you could sail around the world, thus showing that the world was round and you couldn’t fall off the edge. Astronomers figured out that the earth revolves around the sun. After all of this, everybody with a brain realized that the earth wasn’t flat.
Unfortunately, a few insane or stupid people maintain today that the earth is flat. Ever heard of the Flat Earth Society? It really exists. Here’s the group’s website.
In the late 19th century, Karl Marx and Frederick Engels developed the idea of communism. Although many thinking people rejected the ideas as obviously impossible and contrary to how human nature works, the idea appealed to a lot of desperate people. Starting with the communist takeover of Russia, the idea took over a large part of the globe.
But the idea failed. It didn’t work as promised. Without a market system to supply basic information about how much things were worth and what people wanted, the system fell apart. Central planners couldn’t have enough information and human nature corrupted even the best intentions of the true believers. The Soviet Union collapsed, taking with it the various governments it had controlled and supported.
