The GND with its extensive use of private contractors is basically neoliberal like our current DoD. It is structured almost exactly the same as DoD and with a vague never-ending mission would likely take as much resources to fight an enemy that may honestly always exist. A better policy would be focused upon global trade policies to globally incentivize all countries to choose cleaner infrastructure. This sobering reality is one I certainly found refreshing from the Yang climate worldview than the climate alarmist view that civilization ends if we don't go carbon neutral in 8 years aggressively pushing the GND as a gold standard policy.
Let's just look at one (expensive) idea proposed in the GND:
>Upgrading all existing buildings and building new ones so that they achieve maximum energy efficiency, water efficiency, safety, affordability, comfort, and durability.
How is a directive to upgrade all existing buildings, anything but central planning of an entire industry?
That sounds awfully like a nod towards developers and REITs that you'd get property tax breaks and/or credits if you hit LEED certification levels.
What is the problem with that? It's already a thing, just not nationally. You get that pro-jobs angle for contractors, provide a stop-gap when new construction slows servicing existing owners looking to reduce costs.
You're reading the proposals with an ... impractical eye.
