iirc the Fountainhead has two viewpoints, Roark (heroic architect) and Dominique (Roark's lover). My belief is that Roark is a fake protagonist. It's Dominique who undergoes most of the character growth, as she learns to accept Roark's heroism.

Roark gets kicked out of architecture school for not designing in a neoclassical style, then continually loses jobs or has to fight others to achieve his vision. He's suffering like a protagonist, but it doesn't actually lead to him changing like a protagonist. His struggles are generally the same—trying to design buildings and having his designs criticized/ruined on superfluous grounds.

Contrast Dominique who goes from Keating (mediocrity) to Wynand (societal success) to Roark (self-actualized man). Dominique's the one who redeems herself by the end of the book.

> I just remember Gault being this rumor hiding off in the wilderness or whatever, then he shows up with his sci-fi engine, drops pages and pages of dialogue, and… wins? I forget how it ends for him, tbh.

Galt invented a perpetual motion machine (supposedly not one) but refuses to give it to pseudo-Communist America and spends all his time doing manual labour. Society collapses because Galt starts a movement to make the genius capitalists of the world go on strike, then he makes a speech at the end to flex on everyone as the world descends into anarchy.

The funniest part is the speech has no relevance to the plot. Society would collapse regardless of Galt making the speech. The speech convinces the government to let Galt take over the country to fix it, but Galt tells the government to pound sand.

The ending of the book is a complete societal collapse so Galt can rebuild from scratch.

Ironically Galt shares his strategy with the Argentinian Trotskyist J. Posadas, who wanted the Soviets to start a nuclear war since the destruction of society would allow the workers to rise up.
