I will say there is a benefit but whether it's a net benefit is not always true as we can't ignore the downsides.
For example, if everyone believes that you can just work hard and succeed, then they may choose to ignore the great disadvantages certain people have. Indeed this isn't just a philosophical issue as this is the reality even in American politics with regard to having social programs.
I think this is actually even true of people whose stories qualify them to become "heroes". Often because they were able to do something they think it must be possible for everyone else without realizing how many things were working in their favor. There's a psychological phenomenon describing how people who went through the same experience as you are actually less likely to help you because for whatever reason, they seem to remember it was being easier than it was.
