In most socialist countries, people can choose if they want to be members of the pioneer movement or not. There are many differences between a pioneer movement, and the scout movement. Scout movements are independent of governments. They are also not controlled by the state. For example, there were no separate organizations for boys and girls. During the time of the USSR, thousands of Young Pioneer camps and Young Pioneer Palaces were built. These could only be used by Young Pioneers. The camps and palaces were also free of charge, it did not cost any money to use them. The government and trade unions sponsored them. There were many newspapers and magazines published for Young Pioneers. Some sold millions of copies.
