Nonsense. Corporate tax rate in Italy is 24% plus 3.9% IRAP. And most every penny of due tax is being collected in most every European country. What you describe perhaps happened 50 years ago.
European will never be united on the way of thinking. Different cultures and custom, that go a long way back.
Tax cheating is a common practice in Europe.
Most Italian restaurants wouldn't even exist without tax evasion, as the Italian government takes more than 60% (I think it's actually 67%) when you add all taxes and fees. So, most of them have "dark cash" flow.
Some europeans have been hiding cash in Switzerland and setting up companies in Luxembourg and UK to hide cash and pay less % for years.
Then it's probably different in Scandinavia. Each country has its own reality, corruption and ethic.
