Yeah that’s an important topic we’re going to have to think about. I think its our natural inclination to give the same rights to simulated brains as for us meatbags, but there’s some really odd perverse outcomes to that to consider too. Basically, virtual people could become tools for real people to exploit our legal and ethical systems—creating virtual populations for voting etc. I’ve written a little on that half way down this article: http://citizensearth.wordpress.com/2014/08/23/is-placing-consciousness-at-the-heart-of-futurist-ethics-a-terrible-mistake-are-there-alternatives/
I think we’ll need to have some sort of split system—some new system of virtual rights in the virtual world for virtual people and meatbag world rights for us meatbags, basically just to account for the profound physical differences between the two worlds. That we can preserve the species and still have an interesting virtual world. Waaay easier said than done though. This is probably going to be one of the trickiest problems since someone said “so, this democracy thing, how’s it going to work exactly?”
I note this is a discussion that’s fairly political (http://wiki.lesswrong.com/wiki/Politics_is_the_Mind-Killer).
I think this is one statement I have difficultly with. If the country concerned doesn’t have an objective to improve the life of people outside the culturally dominant group, its unlikely that migration can be reasonably equated with anything like wealth redistribution. The example of open but very unequal countries given is actually illustrative of that. I don’t think such cases are exceptions to a rule, I think there’s no particular correlation at all.
A number of related issues occur to me:
Speed/volume of effective integration in a country, and its role in reducing cultural factors of inequality.
Welfare / public services budgets and their role as migration incentives
Brain drain as a poor strategy to reduce inequality, and the waste of certain vital skills when they’re located in some rich countries.
Earned things (eg. rights / citizenship) are generally more valued by people. Perhaps initial disadvantage aids integration.
Visible inequality breeds resentment. Perhaps initial disadvantage hinders integration.
Effectiveness of spending on migrants vs foreign aid as a method of improving lives.
Circumstances in which people will work to “pass on” the assistance they receive and use their new advantages to work to assist others.
I don’t think there’s a discrete answer to your question exactly, other than “it depends”, and I don’t want to get into politics, so I’ll leave it at that. Thanks for post.
