the meaning of the song is about micheal's story and the story of countless others that took the same path in life.
the italians living in Italy dream of coming to America (Land of Opportunity) and the Italians living in America dream of one day going back to their roots and seeing the home of their ancestors. perhaps staying at a villa in Tuscany, or even rebuilding their childhood home/villa.
the song is about dreamers thinking that the grass is greener on the other side. only to find out that they are in control of their own destiny and they have the power to realize their dreams....however, if they work really hard and make plenty of sacrifices.
the song is about seizing the opportunities we are given in life.
so....Amo L'America = Loving Life. we ARE what we LOVE :)
