In Germany, you get decent public transportation, great education and healthcare for your tax money. In Italy these things range from tolerable but inefficient to outright useless depending on where you are.
I've also lived in Germany, and while they do love their paperwork and forms you are more or less guaranteed a specific result if you comply with the process, and it happens within a determined time frame. In Italy you can do the same exact process 5 times and get 5 different responses, or simply no response at all as they will happily lose your paperwork over and over. In many cases officials ask for random documents that don't exist and are not listed anywhere as required, simply to make you leave and bother someone else.
I've become convinced however that all of these issues above are actually caused at their core by nepotism, cronyism and corruption. The most incompetent and corrupt get promoted to the top, and the rest are trampled until they give up or leave. There's no future and no opportunity for bright young Italian people.
Where I live businesses still pay protection money to the mafia, openly. Why would any young person want a part of that? This is going to get worse for Italy as young people, who would normally be the catalyst for progress and change, simply leave.
