While your premise, "economically speaking, the red states benefit from the blue states through government redistribution and transfers of capital from blue state savers to red state investments via capital markets", as derived from the study, may be true, your conclusion that the study manifestly "demonstrates that the current polarization in US politics is misguided and counterproductive" is a profound twist and extension of logic, a mangled bridge too far. You might as well have just written, "Let them eat brioche," and been done with it.
