How will American consumer behavior change in the coming decades compared to the past 30 years?

According to David Wessel, American consumers will likely shift from being spendthrift to more thrifty for the next couple of decades. This behavioral change will force the rest of the world to rely more on domestic demand and less on exporting to the United States. Additionally, Wessel predicts an era of greater skepticism toward markets, with increased faith and reliance on government regulation to maintain economic stability. This represents a significant departure from previous beliefs that sophisticated market participants with their own money at stake would keep the system honest.
