The tenth amendment is similar to the ninth in that it talks about the rights given to the people and only to the people. This idea came from the Anti-Federalists that wanted the people to hold all the power except those powers that were delegated to the federal government by the constitution. The tenth amendment protects sovereignty. A lot of the powers that were given to the people come out of the Articles of the Confederation which gave a lot of power to the states.
This image shows that many people have a strong stance on the rights they are allowed. And that many feel the need to control the central government and not allow the federal government to make decisions that affect more than just a few people.
This cartoon depicts how important the rights given to the states and only the states is important and necessary, and the federal government doesn't have the right to intervene in those rights.
