Earlier quoted context omitted.
USA has many temporarily embarrassed millionaires (or billionaires these days).
You should look up the origin of that quote. Not only is it paraphrasing part of a story and not an actual quote, but it's referring to people that voted to enact communist policies and ended up poor, instead of creating a society where everyone had everything they could want. They didn't want to admit that they'd been fooled by the government, so they were the "temporarily embarrassed millionares".
>"Except for the field organizers of strikes, who were pretty tough monkeys and devoted, most of the so-called Communists I met were middle-class, middle-aged people playing a game of dreams. I remember a woman in easy circumstances saying to another even more affluent: 'After the revolution even we will have more, won't we, dear?' Then there was another lover of proletarians who used to raise hell with Sunday picknickers on her property.
>"I guess the trouble was that we didn't have any self-admitted proletarians. Everyone was a temporarily embarrassed capitalist. Maybe the Communists so closely questioned by the investigation committees were a danger to America, but the ones I knew — at least they claimed to be Communists — couldn't have disrupted a Sunday-school picnic. Besides they were too busy fighting among themselves."
