Rome, January 9 - If elected, a Democratic Party (PD) government would want to review Italy's tax system, especially for fairness and transparency, party secretary Pier Luigi Bersani said Wednesday. A PD government would reduce taxes for lower-income earners and shift the burden to those with higher earnings, he said. "Our real problem is the retention rate of taxes and transparency of the tax system," said Bersani. He added that he was not trying to drive the rich out of Italy, but rather to reorganize the system. The center-left PD currently leads in polls.
