That’s a bit odd since it’s not actually a competition but I’ve spent plenty of time in London and Paris and many years in New York and one subway car has more diversity in New York. New York literally has people from every corner of the Earth from Mongolia to Argentina to the Congo to Bangladesh. Chicago, LA and Houston do too. The reason is simple —the nation has been entirely immigrant based for 500 years when the first Spaniards showed up. We’re deep into the multiracial phase at this point. My own kids have a ridiculous mix of genes from all over the world. That’s very American.
