I just started following this stuff. What multicultural society has actually worked out? Besides the ones that take the best and brightest from other countries? Why is diversity good? Growing up in the US this stuff was pushed on us all the time, so I had always believed it. But then you hear of the huge fail that is going on in Europe, it really makes you think. Googling "why is diversity good" comes up with some generic, feel-good sounding answers without anything concrete. The US and Canada are cited as success, but as mentioned before, the benefits of diversity in come from taking the smart ones.
