When I saw your initial comment I figured this was the tome. It's outstanding. I got onto it after hearing an interview with Richard White. He's opinionated and some of the opinions are very insightful.

In the interview he said that there's no such thing as cycles in history (pace Spengler). Instead there are unresolved issues that keep bubbling up over generations. That completely describes America's problems with racism, starting with the original sin of slavery. States rights is another example. The gilded age illustrates many others.

I was sold on the book based on that 30 seconds of the interview alone.

Have you read the entire Oxford US History series? I have the entire series up to 1945, minus 1896-1929 as that hasn't been published yet. we homeschool our children and my plan is to read those over the next two years to base my teaching of US History to our children when they enter high school. Yes, I'm aware that only provides a one author perspective; multiple authors as each book has a different one. Though at 10,000 dense pages it seems sufficient.
