Dear friend, it was the golden goose for the companies: to have true workers at their disposal without the cost of a true hiring contract, without the cost to pay a true salary and servants to make tons of copies and to bring coffee to the bosses. Students sold to slavery. In the case of a small industry, in any way, I can't blame them: the shameful amount of taxes they must pay in Italy and the shameful bureaucracy hinder them to hire and pay a fair salary without getting broken within a few years (or a few months).
