I think that we can not view this situation from "fail" or "success" frames. Everything is connected and we can not look at the problem from one specific narrow prism. For example, in my opinion the fascist movement in Italy is developing because of current economic hardships and issues like unemployment, inflation, etc. These issues fueled the anger of already xenophobic people, I assume, that they are also most likely illiterate or uneducated, because they can not look at the original issues, but blame others for their problems. It is not the weak government who can not provide enough workplaces, wages etc to people to [blame], but immigrants who "took over their jobs and homes". Even though migrants face the same issues with unemployment and poverty. Who is to blame?
Additionally, I don't perceive this "party" as fascist. Inspired by certain historical figure(Mussolini), these uneducated people are confused and mixed up their ethnic nationalism with fascism.
So I want to say that the globalization started just recently and we can not claim that it failed, it is just a progress of integration, and naturally it is hard to accept and adapt, especially for conservationists. But with stronger governance, equipped police and law, everything would work out. The true problem here is not immigrants and globalization, but slow police and lazy government who don't care about even citizens, therefore not working on crime prevention. People, especially from poor backgrounds have less of moral conscience and need constant surveillance. Italian government knowing about huge flow of immigrants did nothing to control the security of citizens, but it is not the fault of other migrants, closing borders would not solve the problem. The multiculturalism needs more efforts than just being concept and open borders without regulations.
They also think that by being "fascist", they will make Italy great again. But how? They are using the painful examples of people to gain sympathy and take over the government, but in fact even if they were elected, they wouldn't change the already existing system for the sake of being isolated or intervened.
