I agree with your overall point, but putting in effort accounts for much more than 1% of success in pretty much any domain I can think of. there's a sizable chunk of middle and upper-middle class families that can afford to send their children to good schools but not to support them indefinitely. it's a big advantage to start out as one of those children, but it can fall apart at pretty much any point if the child isn't willing to put in the bare minimum effort to advance through the pipeline.
