> only 30 out of more than 6000 have succeded

At becoming billionaires. Many more than that succeeded at making a good chunk of money that was life-changing for them, their families, their early employees, etc.

So I think your reading of the chance of "hope" are overly cynical. Of course it's not easy to make millions, but it's not so bleak and the market isn't so ruthless that it can't be done for those who try intelligently and persistently.

And of course, even below that level of wealth, there are tens of millions of people who work regular jobs and are able to afford pretty high standards of comfort and living by any yard stick that's ever been used to measure.
