"Back fire" is an interesting choice of words. Would you prefer we endeavor to improve children's self-esteem by telling them their failures are out of their control?
I am concerned this both hyper-coddles them and encourages a victim mindset. It's a trade-off in the cases of people with worryingly low self-esteem -- I wouldn't say it's a "back fire", it's just we now have to choose precisely which bad thing happens to people with low self-esteem. The choice sucks, but let's not draw a false equivalency because it sucks.
