What if (IF!) there was an imbalance, and the people of the state felt as though Milwaukee were sucking them dry, and Walker was merely leveling the playing field? Same behavior pattern as, say, Washington D.C. draining the rest of the country, in the vampire fashion?
That is quite an IF statement there. We already know that on the national level it does not parse out the way you want it to; the states with the highest ratio of (money back from the federal government) : (money paid to federal government in taxes) are all in the south where people are bitching that the federal government is holding them down.
Of course we all know that conservative capitalism depends on keeping some economic classes down as allowing everyone to prosper is bad for business. Setting up a deliberately crippling tax system to prevent people from climbing the socio-economic ladder is one way to do that. Making sure that quality education is only available to certain voting classes is another (that goes hand-in-hand with the previous).
