Oligarchy: Government by a small group of people,
Now that is a broadly descriptive term!
By itself it is neither positive nor negative. It is simply a statement of fact - or is it? Start defining the words. Then compare them to our US Constitution and Bill of Rights, and you may start to wonder: Who has the real power? Is that good and lawful? Does it improve our lives?
Does the word just restate an old adage "Money talks."? It appears to buy public office, as in "Whoever can afford the most TV ads usually wins the election." That makes it a handy epithet in a political dog-fight. Or maybe it's more than that. Perhaps it describes a situation that needs to be changed.
Cartoonists have loved the word in the past, and the current political situation in the US seems to offer an opportunity to revive it.
Think about the word and the coming mid-term elections. Is there any relationship? And don't forget, the presidential race is just two years away with the incumbent ineligible for re-election.
