I think it's a mixture of it being cosplay and these folks being extreme believers in capitalism, in the inevitability of it and impossibility of any alternative. They are all successful grifters, and they didn't get there through some scheming and clever deception, they got there through sincere beliefs that aligned with the party line.

They don't believe that anything can actually be done about this progression towards doom, just as much as they don't properly believe in the doom.
