That's true. And cheered by western intellectuals. Mao was probably the worst offender in that respect. Who were Maoist sympathisers in the US and western europe? Not factory workers and peasants.
Very few Western elites were pro-Mao. And general support for communism definitely had a class bias. (Any populism does, for very sympathetic and not-stupid reasons.)
But to generalize this to say that most of Europe's elite supported Mao, or even that American elites supported Mao, is simply unsupported.
