La realidad es que casi todas las agencias tienen menos participantes (por la baja poblacional) y son menos eficientes, pero tienen más presupuesto. Solo a la UPR y a los municipios la JCF @fomb les cortó la cabeza. Por eso es austeridad ideológica, no matemática
Jose Medina Calderon@medinajose75
@COSUAM @CaraballoCueto La baja poblacional, el cambio de interes en estudios y que Recintos con memos de 1k estudiantes, no es percepcion ideologica , es realidad economica y que los contribuyentes no pueden sostener sistemas ineficientes. La realidad economica, actuarà. Realidad Dura, pero real.
