Let’s concede the point: humans are inherently greedy and selfish.
But greed and selfishness are bad, right? We want less greed and selfishness in the world.
Given these two assumptions—humans are greedy, greed is bad—shouldn’t we architect society to explicitly disincentivize greed?
It’s extremely easy, you just install AdGuard.
In the US you either had unlimited SMS or no SMS plan at all, in which case you got charged for every single message, sent or received. But I remember having unlimited SMS as early as 2003.
If you had no SMS at all then you certainly didn't have a data plan, which ruled out WhatsApp entirely.
That’s easy: unlimited SMS was common on most mobile plans in the US as early as the mid-2000s. Unlike the rest of the world, Americans had no financial incentive to use WhatsApp.
You’re preaching to the choir. “Concede the point” is a figure of speech which means the speaker is going explore an assumption despite not believing it themselves.
My point is that the whole “capitalism is the best economic system we know about because humans are greedy” argument is sophistry. It doesn't even make sense in the context of its own flawed premise.
