>Wealth inequality is the intended effect of that incentive structure though, not a negative one. The idea being that those who provide more to society - more unique skills, better creations, etc should be more wealthy.
Wealth inequality is the mechanism by which the incentives are supposed to work, but the goal is still the incentives, not the inequality itself. If it were possible to achieve the same without inequality that would be better.
But you say they "should" be wealthy, are you suggesting a model of morality that prefers rewarding merit rather than improving outcomes (even in the long term)?
>To hamper them in any way would arguably make many lives much worse. And what you're suggesting poses that risk. We could lose out on many such advances.
Or we could find out that the excessive inequality was unnecessary, and that we've been giving people shitty lives for no good reason. Or we could even find out that happy people are far more productive than people terrified of poverty. These possibilities are just as much a risk as your suggested outcome.
Personally, I'm inclined to think it would be far better for technological progress to ensure every person has the resources to educate themselves as much as they want without worrying about survival. And I don't think you need to offer people loads of money to give them an incentive to try and cure cancer.
> it's a lot more of a delicate balance than many people make it out to be. You need to be careful to keep those top performers extremely motivated to do more.
At a certain point, inequality can start to act against motivation, because the richest will continue to live in luxury almost regardless of what they do. Higher taxes (and ideally wealth taxes rather than income taxes) can actually encourage them to keep expending effort so they can maintain their standard of living.
