I don't think this is accurate. I can't point to a source right now, but I have read a lot about the revolution in the last decade and my impression was that some of the revolutionaries were Marxists, but there was no official ideology and Cuba became Marxist perhaps a year after the revolution. This involved a power struggle and some revolutionaries emigrated or went to prison. Castro eventually sided with the communists (Che, Raúl).

Packaging wasn't critical. That's my point: without the product (the Foreign meddling + social fragility) there wouldn't have been anything around for being packaged.

If you blame the atrocities committed on the packaging alone and not on the market that was created beforehand, you're not provinding any help to make sure history doesn't repeat itself.

A lot of people would say that, actually. World leaders throughout history have always picked up religions, ideologies as a way to get additional support, not because it's something they believe in or want implemented.
