Until the 14th amendment, this was not true. As soon as you accept incorporation, federalism/states rights goes out the window. Hell, without incorporation, the Feds would have no way to create rights--like, for example, a right to abortion. They'd have no say in, for example, religion in schools, etc. Like I said, it's done more harm than good. We'd be better off fighting for our rights at the state level.
“Until the 14th amendment, this was not true. As soon as you accept incorporation, federalism/states rights goes out the window”.
Then why did the framers feel the 10th amendment was necessary? Specific powers of the federal government were granted to it over the states. Why else would the framers feel the need to grant “all the other powers” to the states and the people?
