Much of big business will be perfectly happy to be coopted. This is how fascism operates. Business accepts being the junior partner in return for protected markets and a stable, regulated profit. All they have to do is support the party line and provide enough high paying jobs for grifter pols, their family members and their associates.
At some point, the grifter element becomes large enough that the parasite kills the host.
There is also the risk that the activists, having consolidated a fascist and one-party system with no effective opposition, will take the big step to outright expropriation, at which point business becomes the enemy and the party reaches out to control everything.
Yeah, business complies just like in Nazi Germany when the SS and Brown Shirts looted and burnt Jewish stores. There has to be a stop to it.
