Opposition party PO will likely build an economic policy platform designed to spur growth necessary to fund the nation's social welfare programs, including perhaps a few new offers, the party's new chief economics guru Andrzej Rzonca admitted for the daily Gazeta Wyborcza. Recent social spending vows from party leader Grzegorz Schetyna, including a promise to add a so-called '13th-month pension', should not be treated as a complete vision of economic policy, the former MPC member insists. The current government will fail in its pro-growth plans by putting its focus on state-guided investments, he said. A PO government would have to revisit the question of retirement age.
