US GDP Growth: How much is possible?

President Trump and several of his cabinet members and advisors have stated that real US gross domestic product (GDP) growth of over 3 percent, and even 4 to 5 percent, is achievable. NEAM believes 3 percent growth is certainly possible but would be difficult to sustain without some very significant catalysts. We believe the 4 to 5 percent growth numbers bandied about during the campaign are mathematically infeasible when all relevant facts are taken into account.
