Now, over 180 years later, America’s national character seems to be changing. Americans across income classes are moving less, starting fewer businesses, marrying people more like themselves, and basing choices on algorithms that wall them off from anything new or different.

In other words, Americans have become complacent. They are working harder than ever to postpone or avoid change. A focus on safety and caution over everything else has resulted in an America that is less dynamic and more conformist than ever before.
