I don't have a plan. I grew up around many people who had one - they were all firm believers in revolutionary socialism. It didn't work out. I'm not a believer in that.
I do know that neoliberalism clearly isn't in my interests, or those of almost anyone I know. So I'm never going to support it.
I mean, I'm used to people asking me what's my alternative to democratic socialism or social democracy, it's almost shocking to be asked what's my alternative to Thatcherism, especially after it's become clear that it failed at its intended aims ("a property-owning democracy", yeah, that worked out /s).
I'm guessing many here are fine with neoliberalism because it fits their class-interests as affluent middle-class white technocrats. The problem is it turns out that it doesn't benefit a great many others, hence so many, all over the world, now support the likes of Trump. You need a better plan as this one isn't working out too well.
The best I can come up with is that one has to demand the opposite of what one currently has, so as to try and maintain a kind of unstable equilibrium. Capitalism only behaved itself when it was afraid of the threat of communism. Without that threat the plutocrats have run amok, fighting their top-down class-war (neoliberalism being one of the weapons they employ in that war), and the backlash that has led to, seems to be pushing us towards fascism (some of those plutocrats seem quite happy with that outcome *cough* Musk *cough*, thinking they can live with it - probably mistakenly, as with their predecessors in 1930s Germany).
Thus I guess one should demand socialism, despite not really believing it will work (which makes it a very difficult position to hold, admittedly).
