You could use “corporatism” which has kind of taken over that definition

"Neoliberalism" rather. Though that's more like mask-off imperialism. And "corporatism" is just capitalism but when you don't want to admit that the problem is capitalism.

Either way liberalism is the same idealist, individualist culture/ideology that emerges under capitalism to maintain that capitalist mode of production, and must be destroyed along with the mode of production it sustains.
