This FAQ from an American website aimed at people wanting to get their Italian dual citizenship is fascinating ... it's pretty much a puff piece for why anyone would want to be in the EU.

What is the European Union?
The European Union (previously known as the European Community) was founded after the Second World War to ensure peace in the region and to economically unite the nations of Europe.
Today, the EU boasts a fully integrated internal market in which citizens, goods and services can move freely across national borders. Belgium, Germany, France, Italy, Luxembourg and the Netherlands were the six original member states. After five rounds of enlargement (Denmark, Ireland and the United Kingdom in 1973; Greece in 1981; Spain and Portugal in 1986; Austria, Finland and Sweden in 1995; and the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia, Slovenia, Cyprus, Malta, Bulgaria and Romania in 2004-7), as well as the accession of Croatia in 2013, the union currently has 28 member countries.

Do Italian citizens enjoy full EU rights?
Italians are considered citizens of the European Union. As an Italian dual citizen, you would be allowed free movement within the E.U., as well as all benefits to which European Union citizens are entitled.
What is the euro?
The Single European Act (1986) and the Treaty on European Union (1992) introduced the idea of Economic and Monetary Union (EMU) and laid the foundations for a single currency known as the euro. In January of 1999, the euro was introduced though EU citizens continued to use their national currency until euro bank notes and coins were put into circulation on January 1, 2002.
The euro (€) is the official currency of 19 out of 28 EU member countries. These countries are collectively known as the Eurozone, and are comprised of: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. Countries which do not use the euro or with an opt-out are Bulgaria, Croatia, Czech Republic, Denmark, Hungary, Poland, Romania, Sweden, and the United Kingdom.
How can Italian citizenship help my employment prospects?
As an Italian and an American citizen, you will be effectively cleared for employment both within the U.S. and within the greater European Union.
Currently, single citizenship Americans cannot legally work in the E.U. without a visa or sponsorship from their employer. As an E.U. citizen, you would enjoy the full rights and benefits of your Italian passport. This means you don’t need sponsorship for employment, and would be considered a part of the local European candidate pool.
For people with unique skills or backgrounds, this is an immense plus as it allows you to compete for a job without adding an extra burden on a potential employer.
What are the healthcare benefits of having Italian dual citizenship?
Health care in Italy is extremely affordable, even by European Union standards. Though the standard of care varies from region to region (just like state to state in the U.S.), Italian citizens can all expect an affordable, high standard of care.

Does Italian citizenship entitle me to more affordable education?
By and large, the answer is yes.
Education in Italy (and the greater European Union) is far more affordable than education in the United States. There are many world class institutions in the E.U. which charge students very nominal fees. There is one catch: many of these institutions charge different fees for E.U. citizens and everyone else.
As a dual Italian citizen, you would be entitled to the discounted European student rates. For an example, if you wanted to use your Italian citizenship to study in the Netherlands, you would pay around 2,000 euros a year. Contrast that with a single citizenship American who would pay over 15,000. Beyond that, being an Italian (and therefore, European) citizen entitles you to more local financial aid not open to students from other parts of the world.
Can I live elsewhere in the European Union?
Yes!
This is one of the greatest benefits of being an Italian citizen. Having an Italian passport is like having a passport to any EU country, allowing you to live anywhere within its borders. Under the terms of Article 17 (ex Article 8) of the Treaty on the European Union, “any person holding the nationality of a member state is a citizen of the Union.” “EU citizenship, which supplements national citizenship without replacing it, grants citizens the right to move freely and to reside on the territory of the member states” (Article 18).
