You can't really believe that this is what the Founding Fathers intended to be the province of the federal government. If the federal government has the power to tax and spend for whatever it sees fit, then what power is reserved to the states? To the people? Hint: the federal government was meant to be weak and small, not tax and spend without limit.
The power reserved to the states is the power to elect presidents. It used to also be for senators, but sadly that’s to the people. The people have the power to elect the house of repressentatives.
For right or wrong, that’s how it is set up. There really are no specific spending limits in it, it’s setup to allow the voters to elect those that decide it.
