Giacomo Petralia, a former construction worker who was born in Sicily and lives near Bologna, said he wrote about Italian youth for his final exam, ANSA reported Thursday. \"We have to invest in them, even though the public debt is what it is,\" Petralia said. \"You can\'t leave youngsters without a job.\" Petralia said his next step is to attend a university and focus on homeopathic medicine.
