It's nice to think this and there certainly are high-achievers who accomplish this, but Piketty's research relates to the economy as a whole and the entire point is that the economy's aggregate return on capital is outpacing economic growth (r > g). This means even if some do obtain wealth, ultimately there's more losers than winners. Outliers mean little in statistics and economics.
