Is it disingenuous to not think of the United States as an oligarchy when the brother of a former president (their dad was also a former president) has a decent chance of being our next president, as does the wife of a former president? This is all in the last three decades over four administrations.
From Wikipedia: “Oligarchy, meaning ‘few,’ and ‘to rule or to command,’ is a form of power structure in which power effectively rests with a small number of people. These people could be distinguished by royalty, wealth, family ties, education, corporate, or military control. Such states are often controlled by a few prominent families who typically pass their influence from one generation to the next…”
I draw no grand conclusions from this, but it’s worth considering.
