A huge construction project like Trump's wall is a largess of federal spending for the cement and steel industry.
Problem is that wall makes no money.
Highway spending supports the overall wellbeing of the nation same as bridge building.
Why not spend $100 billion? on the US-Mexico Canal for shipping. Share the revenue pro-rata with Mexico's contribution -- they have a lot of cheap labor to give --- then we all make money and the border is secured by a giant moat.
That is faster than going through the Panama Canal. The US-Mexico Canal would be the 8th wonder of the world with TRUMP written all over it
