"How do you get austerity from neoliberalism, a movement that argues that more wealth should trickle down?".
The abundance folks constantly fight the populist left on government spending. Their proposed plan for "having more things built" is to deregulate the housing market and pray that somehow, the massive land owners, who de facto control the political life of this country and have had their way for a century won't fight it.
Absolutely ridiculous claim sorry.
They want SME's running regulations.
Look you can read between whatever lines you want, but Klein specifically calls out the left getting out of their own way. That even when the left tries to do far left top-down socialism, that the regulations and special interests groups prevent them from capitalizing on their own successes.
So even if you come back with something like price controls and government building more housing, you run into the same problems, and you say something like “fuck norms, ignore the neo-libs / conservatives, housing for the people!”
Congratulations, you’ve advocated for deregulation.
