A Debt Agenda for the G7. Martin Feldstein, May 23, 2016, Opinion. "On May 26-27, the heads of the Group of Seven leading industrial countries will gather in Japan to discuss common security and economic problems. A major common problem that deserves their attention is the unsustainable increase in the major developed countries’ national debt. Failure to address the explosion of government borrowing will have adverse effects on the global economy and on debt-burdened countries themselves." Link
