This was another thing Rifkin pointed out:  The EU has developed -- and I noticed this in London -- a sort of alternative to the Melting Pot story of America, in which you have many different cultures that are present together, but that maintain much of their respective identities (less melting, stronger diversity).  It has a lot of appeal.  There are aspects of both on each side of the Atlantic, but it did strike me as an interesting general difference.

Be nice to America. Or we'll bring democracy to your country.
