If you’re saying “money was too tempting”, then isn’t that an inherent flaw in any Marxist Leninist theory in practice?

HA, yes, yes it is. Marxist Leninist works most effectively when everyone is moralistic and considers the larger picture. It doesn’t work when you have a world of selfish money grubbers. Notice which system is winning today?

I’d like to see you own a small business and get offered 10x its value by a large corp. Then you can see whether you want to maintain your praxis or retire on a nice beach somewhere the rest of your life.
