Why Are Italians So Good at Personal Finance?

Why are Italians and Americans of Italian extraction 'over-represented' — to use, sarcastically, an ambiguous word whose very ambiguity endears it to the politically correct — among the fiscally responsible?  Ten reasons.

Sadly, two highly-valued male friends of mine, one a philosopher who does not hike and the other a hiker who does not philosophize, are either clueless or inattentive when it comes to personal finance, like most Americans.  Why do they lack basic common sense about matters monetary? 

Do I enjoy a species of 'white privilege,' namely, 'Italian privilege?'

My use of 'privilege' here is of course derisive.
