It doesn’t have to be sexier terminology, or even different terminology. Just don’t drop the word “liberalism” into a conversation and expect the average person to understand what your talking about.
You could use “corporatism” which has kind of taken over that definition in common language. I know it’s technically incorrect, but language also isn’t static outside of academic disciplines. But ultimately you can use whatever language you want, just don’t assume a particular definition will be understood without explanation.
