* Social security/pension: if you work on IT in Italy, and have any degree but an Engineer one, you must pay 26% (and is planned to rise to 33%!) of your income to a pension public fund called "Gestione Separata": add to this your income tax and see how you say goodbye more then 50% of your money.
That pension fund is a total robbery since it is well known not to be sustainable, so just a miserable pension will come just from that fund. Even the director of the national pension institute (to which the fund belongs) once stated in the press: "I don't even understand why all subscribers to the fund 'Gestione Separata' are not protesting on the street!" (btw: subscribers are millions!).
Even more:
* the fund does not give you anything if you are sick: are you sick? you have to work and pay your pension (no concession!): yes, seriously!
* until 2 years ago that fund did not even give a woman any contribution at all for maternity (!)
Angry with their embarrassing political scenery, many Italians give up and, as they have been doing for centuries, go abroad: "voting with their own feet"
