This measure isn't going to capture everyone, and there will always be outliers who, despite being given every opportunity, still manage to fail or drop-out. If your only mark of success is a 100% hit-rate, then of course you can declare confidence in failure from the very beginning. Fortunately, most people are a little more realistic.
Once you chip away at the elitism of tertiary study through eliminated tuition charges, it becomes a lot easier to advocate for other changes - reduced textbook costs, improved physical access, etc etc. Free community college isn't the full picture, but it's a great start.
