If we understand the fiat money regime, Bernie&#x27;s proposal is reasonable; that is, one does not need to get $18T from the taxation. The real constraints for any nation are real resources(labor, natural resources, for instance). What Bernie critics appeal to the limitations of financial resources(&#x27;money&#x27;).<p>The dominant economic thought in the states, the thought shared by both liberal and conservative economists, is called &#x27;sound&#x27; finance: you can&#x27;t finance a government unless you borrow or tax. There is an alternative thought, which is sounder than this &#x27;sound&#x27; finance: it is Abba Lerner&#x27;s functional finance. Modern Monetary theory (MMT) combines  functional finance, with stock-flow consistent modelling pioneered by Old-school Kenynesian (not neo-Keynsian) Wynne Godley.<p>Read MMT to understand why Bernie&#x27;s stance is reasonable. WSJ, NYT, WaPo, etc, all represent the sound finance school, sold by the elite and their cronies on the left and the right.
