Depends where in Europe you are.

$80k in London as a single 20-something is great and you might be able to save a little while living central, while for a family of 4 it'd be much tighter and you'd live further out of the city.

$80k in Manchester and you'll have a comfortable life as a family of 4.

$80k in Poland and you'll be laughing in a luxury flat somewhere with no financial worries.

Europe is a large place and for the majority of countries and cities that is enough money to live extremely comfortably.

As for evidence, the average median salary in Europe is 16943€ or $18,947. The average salary in the US is three times this amount so sure - it goes 'a lot further in Europe'.
