Wikipedia has a list of Chinese billionaires. Software Developer salaries in China are similar to salaries in the west. Laborers appear to make far less than owners. I do not know why an individual needs billions. Seems to violate, "from each according to their ability, to each according to their needs".

Maybe the billionaires do not own the capital their laborers use. Maybe the relationship between Chinese billionaire and worker is not exploitative as per the meme. Do the workers control their labor?
