The United States could build a bridge across the Darien Gap, but of course no sacrifice is too great to save the greedy idiot GOP rich and giant corporations from paying their fair share...
Why should the U.S. pay to build a bridge in another country? ...

You'd be opening South America up to millions of opportunist migrants, making it easier for them to head up for the sake of making it a little easier for some American's to travel down by car to South America? sounds a bit irrational and a crazy project when you weigh it up.
