Socialism always collapses into authoritarianism. Socialism sounds nice in theory.. “Everyone will work and contribute and get fair rewards!”, but then a few people don’t work and still get rewards. Other people see that and they quit working too. It spreads like a cancer until few people are working and there is no way to eat or get goods. The leaders are forced to make people work. If you can’t use incentives, you have to use a stick. And thus another socialist utopia falls into a disastrous dictatorship.
