Why then do we need them at all?

I keep hearing republicans insisting government is now too big and power should be given to the states to handle everything. Of course everything that they can sluff off onto the states has to be paid by someone. Oh yeah, thats why taxes keep going up in all of the states and counties and cities, to pay for things federal government should be funding to begin with. Its our money anyway.  If they really believe what they say,,, WHY THEN DO WE NEED THEM AT ALL? Lets ask them all to go home and leave their inflated salaries behind.
