Achievements of Neoliberalism is what you mean.
Even if that’s the case (I’m not sure it is), it doesn’t make them the same thing.
It’s not like there is a law of nature that says Social Liberalism can’t make a comeback.
It’s the evolution of a social system guided by the same set of rules. There is actually a very good reason why social liberalism can’t make a comeback. The dynamic of liberalism that champions private ownership leads to capital accumulation in the hands of the small capital owning minority. As the system continues to function you hit a point where the oligarchs have disproportionate power in society leading to the transition into neoliberalism that we’re living under now.
That’s what happens when you let the capitalist class run the show… on thing they care about are their profits. Building a prosperous society for all? That ain’t their game.
Edit to add: Ah fuck nothing: All those decision makers made off with the bag.
