Natural monopolies are best run by the government.
That's why Mussolini got the trains to run on time. He also used them to ship all the Jews to concentration camps, but what's a few million lives compared to being slightly inconvenienced?
This is false. Italy did not ship its Jews to concentration camps during WWII.
After Italy switches sides, and joined the Allies, the Germans, who quickly occupied northern Italy immediately started carrying out the Holocaust.
They were not very successful, because of resistance and non-cooperation by Italian civilian authorities. Less than 10% of Italy's jewish population died in the Holocaust. (Compared to 50% of Romania's, 90% of Poland's, 70% of Hungary's, 30% of Austria's, and 90% of Greece's)
