The EU sits on Italy, keeping it from escaping poverty; this is driving Italy towards right-wing radicalism.
As long as the EU keeps blocking elected governments from doing anything to help the people that elected them, the people will reject them for their failure and vote for a more radical party.
I see two ways this slide could end: with the election of a party that will confront the EU with an economic hand grenade in its hands and win some concessions, or with the election of a party that will be so repressive that it won't allow people to replace it.
The latter is the only way a party can lastingly impose the ever-increasing suffering that the banksters demand. I fear the Lega will soon get the chance to do that.
