I don't personally feel building infrastructure helps the US grow its economy. What does this even entail?

Faster Network speeds: yes Build more highways: no Building highspeed rail: no Building a better way to transport things: yes building intellectual property: yes

The point is, what sort of infrastructure does the US actually need to build? I personally believe more roads is not one of those things that we should be trying to build. Pretty sure the highway system does an excellent job already.
