A roughly $1 trillion bipartisan infrastructure deal is expected to be on the way. But hold your applause, because the bill has a long way to go before it reaches President Biden’s desk. And American infrastructure is up against one very significant hurdle. It’s more expensive to build here than almost any other country in the world. And costs keep going up. The same mile of highway that cost $8 million to build in the 1960s rose to $30 million by the 1990s. Why? “The headline is, we’re not sure,” Yale professor Zachary Liscow says. “We’ve gotten richer, and richer people demand more expensive things.”
