Modern money is a spreadsheet! It works by computer! When government spends or lends, it does so by adding numbers to private bank accounts. When it taxes, it marks those same accounts down. When it borrows, it shifts funds from a demand deposit (called a reserve account) to savings (called a securities account). And that for practical purposes is all there is. – James K. Galbraith, Introduction to Warren Mosler’s 7 Deadly Innocent Frauds of Economic Policy
