Depends upon how one defines success and failure. For the left, success is the creation of generations of morons, totally dependent upon Big Brother and the democrat party because as students, they have learned nothing but how to put a condom on a cucumber.
They are absolutely designed to produce exactly what they do in terms of product. Anyone who slips through the cracks and manages to get an education is summarily knuckled-down on as they move up through the ranks.
The only way for socialism to succeed is to make people ignorant and unable to meet their own needs.
