Like if you’re okay with your system being contradictory, I can’t prove you wrong, and I don’t aim to change your opinion. I don’t even know how one could prove someone wrong who was already acknowledged in a state of contradiction. If you’re cool with the system, good, have fun.
This is were I think the “moral aspect” factor comes in. It doesn’t really make sense, especially when a lot of the close alternatives will produce worse outcomes, to say “Capitalism is contradictory” unless it’s being used as a moral system.
There are people such as Libertarians and Anarcho-Capitalists who do use it as a moral system, as well as various other right-wingers who don’t understand the true power of AI yet. (The latter group I am having mixed success on winning over.) “Your espoused moral system is contradictory” works as a critique for them, certainly. (I’d go so far as to say that the Anarcho-Capitalists are unwitting enemies of humanity.)
But otherwise, it’s like saying “your elephant is mortal”, and like, I know my elephant is mortal, I’ve looked at a number of elephants and this one and its close relatives were the best ones I could find. I’ve heard people claim immortal elephants exist, but I’ve never seen one.
A lot of individual people have to deal with contradictory demands, sometimes so hard they break. I have enormous compassion for them, and I really want to tell those people “It’s okay. The contradictory demands you face are impossible and I don’t blame you for failing to meet them.”
And it’s good to show these people compassion, but I think the presence of contradictory demands is going to be a thing so long as tradeoffs must be made - and thanks to opportunity cost, which still very much exists under Communism, there are always going to be tradeoffs. In other words, I don’t think Capitalism is particularly special in this regard. (Again, unless one is using it as a moral system.)
Certainly, attempts at Communism have resulted in collisions with reality, where someone is subjected to contradictory expectations, which are partially responsible for the black markets and corruption that resulted.
The other thought is just an empirical one: liberal capitalism is meeting unprecedented challenges. Not from the communism-outside, but from its own polities kicking the outhouse over. You can say some level of contradiction is tolerable for a while, but what do you do when the elephant seems to be finally dying?
The problem is, aside from wage subsidies or basic share/income, which are still within the same species of elephant, I don’t really see a better elephant right now.
