I'm starting to think girls were hotter back in the day. Do you agree or not?

For example, the Mexicans that came in 80's to the United States were from rural regions, in the past this rural regions were settle by Hacendados which were Spaniards. Now I'm seeing people flood that are coming to the United States from those Southern regions, looking less Mestizo. Now as for the Americans it seems like in the past 25 years the Americans homogenous populations have diversified by breeding with other American from different parts of Europe. It also seems Europe is following this and European in the case of French are looking less French, the Greeks looking less Greek, and so and so on.
