If the American people woke up & realized federal income tax was money being sent from their pockets, straight back to paying off the national debt, I bet they would stop paying.
It's LITERALLY a never-ending cycle. The US borrows from the Fed, the Fed charges interest, we give them our "money" right back.
Then, for the returns, the US borrows more notes to be printed to give back to us, which is charged interest as well.
End the fucking fed. Stop paying them. Stop digging yourselves further into debt.
