I think the point is that until someone comes up with a different workable system, then in a mixed capitalist economy such as ours we will alway have the model we have got.
The balance between private and public May differ, largely depending on the colour of the government, but it will remain.
So therefore, it is desirable to have the best system that we can.
How we achieve that is always open to debate 😊, which weirdly I think is a good thing provided any changes actually achieve the desired effect and there isnt change for its own sake, or silly ideological reasons that achieve nothing.
A drop in the ocean in the great schemes of things....but replicated by how many more
