But not that new, "The capitalists will sell us the rope with which we will hang them" is a quote attributed to Lenin, so >100 years old by now
...The earliest strong match located by QI appeared in 1955 within a periodical called “The Commonwealth: Official Journal of the Commonwealth Club of California”. The club is a non-profit public affairs organization. The quotation [by Major George Racey Jordan] appeared as a filler item.If not, it's giving "We're tying ourselves up with the rope the capitalists sold us".
I acknowledge the irony though.
