Economist Justin Wolfers this weekend warned of the long-term damage he believes President Donald Trump is inflicting on the U.S. economy through what he described as “the most interventionist” and, in his view, the “least conservative” government of his lifetime.

But Trump, Wolfers said, is actively undermining all of those foundations.

The consequences, Wolfers warned, will not appear in “next quarter’s GDP” but will instead emerge “in a decade’s time” through companies that are never founded, entrepreneurs who can’t afford business school, and immigrants with transformative ideas who choose to remain in their home countries.

“Whatever the next generation’s Google or OpenAI is, it may not end up being invented or it may not happen on our soil,” Wolfers said.

A longtime critic of Trump’s economic policies, Wolfers predicted the most severe effects will ultimately be felt by future generations.

“Our kids will feel it in a set of lost opportunities,” he said. “There’ll be businesses they never started, there’ll be job opportunities, there’ll be new technologies, there’ll be ways of creating a greener, safer, more prosperous future that simply aren’t possible but we’re not going to see it straight away.”
