“If Trump thinks he can get more than 3% economic growth, he's dreaming,” ran a Los Angeles Times headline. “Trump’s budget assumes 3 percent annual growth. Why that’s extremely unlikely, explained,” explained an Obama economist at Vox.com.
Inc.com cited Marc Goldwein, senior policy director at a liberal budget organization, who ”believes the upper limit of what is reasonable, considering the tax and regulatory reforms being discussed, is probably just over 2 percent. ‘To get to 2.1 percent, 2.2 percent, 2.3 percent – that would be a tremendous feat.’”
"The bottom line," Goldwein said last year, "is we should not be buying magic beans. Three percent growth is not completely impossible. But it would be a heroic feat to get there."
