This comic reminds me of a classic argument used for leftist policies, unrelated to ayn rand though. Under capitalism, technological advancements are harmful to the working class because companies are likely to keep pay and hours the same, and just scale up production and/or lay off surplus labor force.
Under a system where the workers own the means of production, those same advancements could go towards lowering the hours of the employees without lowering their pay, or if they decide to scale up production then it would mean more profit that the company could decide democratically what to do with, making it likely to result in pay increases for the workers. Point is it wouldn’t just go into the hands of the capitalist class, but rather stay under control of those who labored for it.
