Not an Italian luxury car.
No. Pareto was the Italian economist that came up with the 80/20 rule. He figured out 20% of the richest families held 80% of the wealth (this is probably worse nowadays). More generally stated, the 80/20 rule says that 80% of the results come from 20% of the inputs, you spend 80% of your time doing 20% of your tasks, etc, etc.
