Sorry for the late reply. Thank you for the answer, I have not spent as much time in Italy as I would like to, but from what I hear from relatives and online, the situation is not very good and getting worse.
I am Italian only by citizenship and heritage (Not by culture really), what parts of Italy do you suggest? I might visit Valle D'Aosta soon.
Yes the situation is not good and getting worse, but if you have the money and if you come out with a good plan, you can live a quality life.
The situation is bad for the Italian people that work as employee (they give 60% of their salary in taxes and they don't get enough money for a quality life) and for small-medium entrepreneurs (they pay 60-70% in taxes and they fight every day against bureaucracy and the fucking government/revenue authority).
So if you have the money and if you don't work in Italy or you don't run a business in Italy, yes you can live there pretty well.
You can go with flat-tax (100K/year) or pay 26% on capital gain or dividends from abroad.
26% makes you angry but you must to consider that the cost for house is 1/3 compared to Switzerland, Dubai, etc and cost of living is 1/2.
If you are High net worth you can go with flat tax (100K/year), if you are pretty wealthy you can go with normal taxation (26% con capital gain and dividends from abroad).
If you like mountains and a cold winter I would recommend you to go near Como or Trento or Bolzano.
If you prefer plains, I would recommend to go in south Garda lake area, or Parma or Bologna. Personally I prefer to stay close but outside the city.
In those places you can buy a small/medium villa with swimming pool, garage, etc from 400k to 800k eur.
If choose those locations, you install cameras, alarm and you pay private guards patrolling the neighborhood, I think you could be safe and pretty happy, personally I would be.
There are thieves all over Italy but you just need to take precautions and avoid problems.
About Valle D'Aosta could be nice if you like mountains, cold winter and living pretty insulated.
Stay away and avoid the biggest cities, there are like a jungle.
