Someone who buys the ladder, then sells the rungs behind them.

means A person who wields power because of their wealth, in a society effectively ruled by the rich.

from Built from Greek ploutos, 'wealth' (also the root of Pluto as god of riches, confusingly distinct from Pluto the underworld god, Plouton), plus -kratia, 'rule' or 'power' — the same suffix that gives us democrat and aristocrat. The word plutocracy surfaces in the 1600s, but 'plutocrat' itself is a 19th-century coinage, sharpened into a political insult once industrial fortunes started buying elections and newspapers rather than just mansions.
