One of my pet peeves is when someone takes issue with an oversimplification of something, but instead of dealing with the oversimplification, they keep the same level of oversimplification but assume that the opposite view must be true. Just because something's not 100% true doesn't mean it's 0% true. In this case, a more appropriate level of granularity would be: "if you work hard, you are more likely to be successful than if you don't work hard." That kind of nuance doesn't really resonate with children though, which is why we don't tell them that. Complaining that it's all a big lie is akin to someone growing up, realizing that there is no Santa living in the North Pole, and concluding that the North Pole must also be a lie.
