Congress is not empowered to tax for those purposes which are within the exclusive province of the States. Justice John Marshall, Gibbons v. Ogden, 1824.
So when the anti-constitutional Progressive Movemnent tricked citizens who didnt understand the federal governments constitutionally limited powers into pressuring their state lawmakers to ratify the 17th Amendment, the states were then at the mercy of corrupt, popularly-elected federal senators who voted to pass constitutionally indefensible House appropriations bills, bills which Congress couldnt justify under its constitutional Article I, Section 8-limited powers. So corrupt Congress was free to start making constitutionally indefensible laws which stole both state powers and state revenues associated with those laws.
So the states cannot experiment their own social spending programs as the Founding States had likely intended because corrupt Congress is stealing state revenues indirectly by means of constitutionally indefensible federal taxes.
Are we having fun yet? 8^P
Ping. It’s only political theater, but it may start a discussion.
