Marx is incredibly helpful in most things as long as you realize that he managed to identify the right problem (which I referenced by the quote), not necessarily the solution; and that his proposed solutions have never been properly tested, and that his ideas for the solution to the problem were -- just like Nietzsche's ideas -- bastardized by terrible people for their own gain. You don't have to be a communist to realize that Marx was instrumental in giving us the labor movement, including unions which most people who haven't been indoctrinated over generations with red scare tactics will realize where good things and important mechanisms against overreach by the powerful.
