"Other People's Money" coined by Brandeis in 1914. [fact]
Fittingly, considering the U-shaped financial history previously discussed, the source of this phrase is likely Louis Brandeis's influential book from 1914, Other People's Money and How the Bankers Use It, a critical analysis of banking, monopoly, and the "financial oligarchy."
XREF: Links to the earlier discussion of the U-shaped financial history, connecting specific language to that broader arc.
