I gave a concrete example to the affirmative to a different commenter, so strictly speaking, yes. Arguably many European politicians don't say this but advocate for policies whose immediate logical conclusion is stagnation or decreasing growth. One example to demonstrate the point is banning fossil fuels (not debating the merits of it, but to demonstrate the point). In fact, the writing of Abundance is implicitly acknowledging such policies are in place.
But that was not the main point: there is a difference in basing your ideology on top of that pillar and betting the farm on it ala Abundance vs. just thinking economic growth is a nice to have blessing.
You're making a fantastic argument for why your earlier accusation that Ezra is advocating "the core ideas of the current administration" is completely ludicrous.
All of MAGA's most core policies are fundamentally degrowth. Tariffs, cancelling the CHIPS act, cutting funding for medical research, pushing expensive fossil fuels like coal above cheaper renewables or even natural gas, pushing resource extraction and commodity manufacturing and agriculture at the expense of advanced manufacturing.
The outcome of all of those policies will be degrowth, even if Trump isn't using that rhetoric.
