Yes. Even our economic success is largely downstream of America’s founding culture.
In the book “What’s the Matter with Kansas?” Thomas Frank spends hundreds of pages being confused why poor Whites don’t vote for socialist policies they would directly benefit from.
But this attitude, this fierce insistence on personal responsibility, on principle over handouts even among struggling people, is why we are so rich.
America’s culture, grown from British roots, is the best and most successful culture in the world. It does not need to be “improved” via dilution by less successful cultures (all others). We should be proud of it. We must insist on maintaining it.
