Laffitte’s law

The XIX^th century French banker Laffitte is renowned –between other things—for saying: “a rich idiot is a rich; a poor idiot is an idiot”.

I suggest we call this structure “Laffitte’s law”.

Examples: for a French, a disciplined French is disciplined; a disciplined German is German… right?

Or: for an American, an American idiot is an idiot, a French idiot is a French—no?

This kind of “contamination” we do all the time, unknowingly.
