A group of nearly 1500 economists have sent a letter to President Donald Trump and congressional leaders touting the importance of immigration to the U.S. economy.

The letter was sent through the organization New American Economy, an group comprised of Republicans, Democrats, business leaders and Independent mayors.

The letter was signed by 1470 economists from all walks of life. They were advocating four essential benefits of immigration:

  • Immigration brings entrepreneurs who start new businesses that hire American Workers.
  • Immigration brings young workers who help offset the large-scale retirement of baby boomers.
  • Immigration brings diverse skill sets that keep our workforce flexible, help companies grow, and increase the productivity of American workers.
  • Immigrants are far more likely to work in innovative, job-creating fields such as science, technology, engineering, and math that create life-improving products and drive economic growth.

The economists admitted that immigration comes at a cost, “particularly for Americans in certain industries and Americans with lower levels of educational attainment. But the benefits that immigration brings to society far outweigh their costs, and smart immigration policy could better maximize the benefits of immigration while reducing costs.”
