Thank you for number 10. I am so tired of the narrative that diversity is the be all and end all for why this country achieved greatness. That is simply untrue. Assimilation of groups made this country great, the melting pot. People working to achieve the very best they could as individuals with a common language (english) and learning a common history and traditions. Yes we did incorporate what fit and improved the american experience but cast aside a great deal of the ideas and traditions that did not improve our lot. We were selective and people either got on board or were left behind. The new comers learned to fit us not the other way around.
