By Tatiana Jancarikova NITRA, Slovakia (Reuters) - Bozena Vargova, a retired physiotherapist from Slovakia, cannot understand why her country should bail out Greeks who often earn twice as much as Slovaks and run up debts. In the bitter wrangling over whether the euro zone should bail out Greece, some people sympathetic to Athens framed the debate as a stand-off between Europe's rich and poor: wealthy Germany humiliating poverty-stricken Greece. Sixty-year-old Vargova, and her husband, who works as a masseur, have sold their four-room apartment in Nitra and moved to a cheaper house in a nearby village to eke out their limited funds.
