So has capitalism. What's your point?
Just because something was done poorly in the past doesn't mean we can't iterate and improve. Capitalism has no ready answer for some of the problems we are beginning to face. Eventually people like you are going to have to admit that Marx was definitely right about at least one thing: socio-economic class is a critical social cleavage that drives much of history.
So unless capitalism figures out a way to pull its stubborn head out of the sand and deal with its own shortcomings to prevent society from tearing itself apart, we're going to get a chance to find out whether Marx was right about anything else.
