The point was "you don't understand how theory and reality aren't the same".

Everyone knows that. So did you made a point that no one disputes? Very well, but feel free to make the point that pro-wall street, pro-military industrial complex politicians are actually "Marxist" because you were told to call them that.

And what's the difference here? A thin layer of deniability with the rich and powerful owning businesses and the government?

Well, there's a rather large difference between the government owning all means of production, and the rich and powerful owning the government. The fact that they both boil down to being rather bad things, does not make them equivalent, let alone the same.
