I (mostly) agree. It would seem that to do infrastructure especially in the middle of a recession (when you might be able to get it done cheaper) is the time to do it. That being said, you have to layer on the inevitable inefficiencies/corruption when such projects are rushed in order to have any impact to a recession.

I wonder if there are more creative ways to go about it like encouraging private firm participation through road privatization (which means that you get the same impacts without the government spend from private firms that are incentivized to be more efficient to maximize ROI). There are also creative experiments like congestion pricing that have the potential to greatly recoup costs while improving productivity.

There also obviously environmental impacts though of cheap free roads which have also been blamed for enabling urban sprawl. Again, it would just seem to me that yes, infrastructure is important (and much of the existing infrastructure is aging and needs to be replaced) but the way that we've gone about building it in the past and in how it's being proposed to build out now as stimulus, is less than optimal.
