When you multiply the productivity of every practitioner of a trade, they can lower their prices.
I’m sorry, but that’s some hilarious Ayn Rand thinking. Prices didn’t go down in grocery stores that added self-checkout, they just made more profit. Companies these days are perfectly comfortable keeping the price the same (or raising them) and just cutting their overhead.
Don’t get me wrong, if there are things they could get more profit by selling more, then they likely would. But I think those items are few and far between. Everything else they just make more money with less workers.
You’re focusing too much on the “rights” and not enough on the “Mah.” Not “Our rights.”
It was never about universal rights. They were pretty clear about them caring specifically and only about their rights.
