Jacob Gichan for Economic Policies for the 21st Century: American infrastructure needs significant improvement, and President Trump plans to encourage the private sector to ramp up investments.

The American Society of Civil Engineers has given U.S. infrastructure a D+ rating, estimating that between 2016 and 2025 the U.S. will need approximately $3 trillion in infrastructure spending, two-thirds of which is needed for transportation. The society further expects that there will be nearly a $1.5 trillion funding gap. Private equity can step in.
