I do not know if they will be net positive, it depends on metric the comparison is made with. I think on pure economic side it is not beneficial for GDP growth. Just take EU and compare it with US. I think the system in US is more fair and closer to true, fair value of labor.
But I think the fair world is a world without compassion and with huge separation between rich and poor. I think on ethical grounds we should make the world less fair, more equalized, despite of the fact that it reduces GDP growth, because there are other metrics possible, like human happiness and well being.
Our conversation started from me noticing that people in this discussion expecting that fair value for labor is higher than what is typically paid. And I think the reverse is true because there are things that artificially increase wages, like minimum wage in many states. So, “be careful what you wish for” kind of thing.
