The lie of capitalism is that hard work always leads to success. There's only so much opportunity to go around. If all the kids aim to be President of the United States, most of them will be thwarted. You can work as hard as you like at that, but a vast number of you will still fail - even some who are perfectly suited for it. But die-hard capitalists believe they are living in a meritocracy where hard work leads to success and success is the only measure of whether you've worked hard. Also, if you succeed, it is 100% due to hard work and no luck at all. It is, quite simply, not true.

PS - No work at all, of course, leads to failure.
