It's pretty obvious really. It's a numbers game. On an individual level you might be able to make a difference, just in the same way that someone wins a jackpot on the lottery. By definition not everyone can win the jackpot on the lottery though, the maths tells us that. It relies on people failing with the odd successful winner. The idea that everyone has absolute control over what can and what cannot be is somewhat naive. Right skills, right time, right place -- and if you happen to be born into money you've got one hell of an advantage, it tends to give one a bit more control. Hard work in itself can be a very blunt tool, even foolish. I could work at my athletic sprinting 15 hours per day, 7 days per week but at 5' 7" I'm never going to catch even a local club sprinter. I could try but ultimately it would be a complete waste of time and effort if my objective was to be the fastest person on planet earth. I could reach my personal peak, much quicker than when I started out. Both a failure and a success. We shouldn't be afraid of either.
