Infrastructure price tags always sound like huge unthinkable numbers. ONE HUNDRED BILLION DOLLARS. And it is true that it is hard for state and local governments to come up with that kind of money. For the federal government it is chump change, even leaving aside some more creative ways of paying for it.
Once upon a time the US really was ahead of basically every other country in the world. It was shiny and new. We had shiny new highways, our cities weren't bombed out by wars (though we did a pretty good job subsequently at destroying them ourselves), lower middle class people had things like refrigerator/freezers and cars, and potable water coming out of the tap was the norm. Things were clean. We had nice affordable hospitals. It was an understandable symbol of progress, of modernity.
Now much of the world has those things, along with in some cases some things are more humane and appealing. I don't think Trump is really talking about BUILD MORE SUPERTRAIN TUNNELS when he says "make America great again," but it is the case that the country isn't shiny and new like it was. The Reagan era made nice things, even fixing nice things, unpossible for going on 40 years now. Something has to change.
