Creating new public infrastructure in the US can be extremely expensive, but it’s definitely still worth pursuing.
Nearly every in-depth study shows that for every $1 invested, the economic return is somewhere around $4-$5. And on top of that, failing to have adequate public infrastructure can cause serious economic consequences, which are compounded in areas with a lack of affordable housing.
Even though this article is a little old and sponsored by a party with a vested interest on the topic, I think it’s worth a read:
In my opinion, the problem for the US is convincing people/businesses that it’s worth it. Shifting away from cars and increasing investments in public infrastructure are two fairly unpopular measures right now, despite the actual economic evidence being overwhelming positive.
To me, it’s a solid example of where great leaders are needed to do something temporarily unpopular for the long term benefit of the constituents.
