Us. Our culture.
FWIW I'll try to explain a little more. I mean, that's a great question but I think it's the wrong question, if you don't mind me saying that.
Nobody can see outside the logic of their own epoch.
Capitalism can't be "fixed", because it's just what it is. If we "fixed" it, it wouldn't be capitalism any more, it would be something else. In fact it's been many different things over the past centuries as it transforms, much as people like Smith and Marx predicted.
Most people at this point say "Okay, smarty.. so what will you replace it with?". And again, wrong question. There is no list of "systems" that could simply be plugged in as replacements. That kind of nonsense leads to great leaps into famine and 20 million starving. Politics is not software like that. At best it's a set of potential slow paths that all start at where we are now. It is not even a set of destinations, because every end point we pursue changes with the dynamics of time and change itself.
The question, as I see it, is what do we change in ourselves to make capitalism work. What makes capitalism into a non-toxic system that does not destroy our planet and lead us to perpetual cycles of war, and misery and self-hatred?
Now if you want to talk about that list... that's another conversation.
That's not the same as changing culture. That by definition must change.

Are you familiar with the work of Meadows? She gives names to each of these levels and sets up a relation between them.
Here's a couple of digs into that if you're interested [0,1]
