Billionaires are billionaires not by literally storing cash. The rest of the society values their contributions and creations in the companies/corporations they run. Sure, they have some liquidity but the entire concept of resentment towards billionaires is essentially equal to resentment for the betterment of the world. There are some exceptions but for the most part, in a well oiled market, you can't just become a billionaire by fucking over people.
