> We see a nation used to quick and easy growth from top/down government investments in infrastructure now struggling under the maintenance burden of all that unproductive asphalt, steel and concrete. The simple Jacobin solution of an additional $400 billion per year wouldn't address this problem; it would make the problem way, way worse.

I’m not sure if I really understand this part. But I’m familiar with StrongTowns cause (parafrasing):

There is a lot of public infrastructure build (roads, power, water, sewage, drainage)for land that will never provide enough tax revenue per square foot to pay for maintenance of said infrastructure. This will bankrupt cities and towns.
