I’m going with idiot. He was born into a very wealthy family and was a figurehead in the business which more despite him than because of him is still making money. Whereas he seemed hell bent on making losses.
His “style” of management got him noticed by television which upped his “popularity”, he made some idiotic boasts which by good fortune, read spending a fortune, got him elected by appealing where politicians don’t appeal to. Whipping the disenfranchised into a frenzy, while caring not a jot.
He is now surrounded by a large group of people who seem only to be making sense of his idiotic ramblings on the world stage.
So yes a rich idiot who bought lots of power and now is worryingly in power. Bojo is a poor man’s (it’s all relative) version.
