In non-wonk mode, Bush focuses on how big-picture immigration policy ought to work and how immigration impacts the United States in general.

In the latter chapters of Immigration Wars, a book he co-authored with Goldwater Institute attorney Clint Bolick, Bush writes in general about why he believes immigration is a social good and why the status quo hurts businesses and would-be citizens. He also makes the case for letting more immigrants come into the country legally.

“Left to its own devices and without increased immigration, America’s population is shrinking and aging,” Bush and Bolick write. “We need more immigrants to stem that debilitating demographic tide. We believe there will be less opposition to increased immigration if Americans perceive the need for and the value of immigration—which will happen if we fix our system so that most who enter our country add tangible value.”
