The racist OG MAGA is pissed off because they thought they'd get to run the show once Trump was in and to an extent they are, Steven Miller is a hood wearing racist who gets to make his disgusting dream of containment camps come true with Texas, also run by racists like Cruz, Paxton and Abbot helping get them some land, offered to them by another racist shit bag to build that den of horrors on and Trump is going to do those deportations and captures as much as he's gonna do the tariffs, not because he cares about the country he's doing it so corporations can bribe him to excempt them from the tariffs which is already happening with Amazon and a few other corporations making big donations and bribes to him to get on the exception list and to have their labor overlooked by Trump and miller's racist ass administration.
So Bannon is getting what he wanted, he's just mad that it's still not extreme enough for him or those like him and that the only people benefiting from this money wise are the tech bro billionaires who already have all the money, see Bannon desperately wants to get in the big club, as does the rest of these grifters, tons of money, power and the ability to make their fucked up dreams come true, only now they're finding out they were useful idiots all along.
