A capitalist remains wealthy by M-C-M. M-C-M’ (Money-Commodity- more money than capital you started with) is the strategy used by the wealthy people to increase their wealth by keeping it. They have surplus of money. They use their money to acquire commodities and sold them for a higher sum of money. For example, a wealthy person invests his money in purchasing many real estates. He rent out these properties to working class people by charging them a fee. He not only gets money from the rent, but also grows his assets overtime and grows his capital.
