The Minister of Economy and presidential candidate of Unión por la Patria (UxP), Sergio Massa, announced this Sunday the payment in three installments of a reinforcement of 45 thousand pesos for retirees with income of up to one and a half times the minimum salary, during an act in which he guaranteed that if he comes to power the PAMI will not be closed or the AFJP system will not be returned.   "A country that has no memory, has no future," said Massa at an event held in the Buenos Aires district of Hurlingham, where he was accompanied by the head of PAMI, Luana Volnovich.   The minister clarified that the aid of 45 thousand pesos will be paid in three installments for all retirees and pensioners, affiliated with PAMI and who receive a remuneration equivalent to a minimum monthly salary and a half.   The person in charge of the economic portfolio stated that the reinforcement he gave to retirees was made possible with financing from a tax on imports.   "This was done with a surplus obtained by PAMI and with a tax on imports to defend Argentine work and be able to finance our retirees," he said.   "I want to ask you to defend with your vote, talking to your family, to explain to them that not having the Living Better (program) means 20 thousand pesos more per month in the basket of a retiree," he expressed in front of an auditorium full of older adults.   The head of the Treasury Palace also anticipated that "in a few more days we will see more hospitals operating that were stopped in recent years."
