Add 20 Senators

Give them to new mini-states, allow regional associations.  Then swap out some federal debt to regional banks with local money creation power. Do the trade, we make 20 new senators, but some of that debt is distribted down. California mini states should get six, make that 6, new Senators.  Keep central governmnet income at 15%, but move as much debt down, peranently.

I would say that central government should be funded only with a wealth tax. Central government is used seldom by the wealthy when they have to pay for it.  But, in the trade, we get balanced access to the Senate, for a while.  It mets the condition of greater variability by a simple adjacent move. And the wealthy get their central government with greatly reduced debt. And there is no fear that some obscure senator from some obscure state calling for some obscure war.
