If you talk about tech, maybe. But I don't think the salary situation in Italy is that bleak if we look at the whole economy and account for purchasing power parity. Using OECD's number for 2019, household disposable income incl. social transfers in kind, in US dollars/capita at current prices and PPPs for the countries you mentioned are:
Italy: 31.7k
Norway: 40.1k
Germany: 41.0k
Switzerland: 41.1k
United States: 54.9k
