I think it is not trolling. But I think big concepts as Capitalism have many interpretations, so it is hart to define capitalism in a way that two people understand the same thing.

And as every country, there is never perfection of a system clearly. So USA can be mostly capitalist, while failing in some parts. And this is the same with every country. Because these are only constructions of faulty humans.

And since there is no existing perfect implementation, it is hard to see, what would be perfect capitalist policy.
