What are some presentday examples of trade leading to cultural exchange?
Here's one example --
My son, like many others, has spent quite a bit of time in Japan on business. He learned to like sushi -- and apparently he's not alone because even here in a small midwestern city, my local grocery store has fresh sushi all the time.
Another example --
One of my granddaughters has been working at Paris Disney for several months. She's learning a lot of their customs from her new friends -- and of course they're learning a lot from her.
And of course -- we know that Coke, Pepsi, McDonald's, KFC, etc. sell their products around the world.
