Whatever happens will be painful. And that is the problem for politicians.
Short term more pain for eventual relief is a hard concept to sell. There are no easy answers.
So it is likely to take a collapse into capital controls forced by a confidence run on bonds, for italy to take the decision to start using the minibot renamed the lira to allow trade to flow again without euro..
Salvini says he hopes to reform the EU from within, but without the monetary discipline the edifice will also collapse in a different way. The future is written in the existing history of previous european currency failures.
But the only way that escapes the pain - eventually - is going to back to a lira so that the debts are reduced by exchange rate, and trade starts to balance. that is the safety valve that should work to push up a deutsche mark to make german import far too expensive. So boosting local manufacture of what was immported.
You can imagine how rude the EU will be to anyone challenging their demand to control italy.
There is no hope at present.
