This is more of an ideal than a reality. Anyone can create wealth, but it's not so simple to convince someone to give you money for it. A lot of value is generated and given away for free (Open source is perfect example. Other people might point to the work involved in raising children or running a home), and plenty of people manage to gain control of bootloads of money without providing any value (or even negative value).

A free market is an approximation of value at the best of times: at best it represents people's estimation of that value given the information available to them. But in real societies it's not even that good, it's distorted by power differentials. One of the most significant being wealth disparities. In a hypothetical society where everyone had equal wealth then a market does distribute wealth to at those people who others think are providing value. But as soon as there's a wealth disparity then people with more wealth have proportionally say over where money gets distributed and thus money accrues to what those people consider valuable. The greater the wealth disparities that exist the further away this gets from distributing money to those who truly create wealth.
