For those that talk about giving people things they "have not earned", I note what we've taken from those same people -- the ability for them fend for themselves and live off the land.

With regard to the mechanism of "compensating for the lease of the part of our living planet they should be entitled by birth", I think any means tested or regulated approach is problematic. Instead provide to them rent checks for the slice of the world society has taken from them, and provided to others for private ownership / exploitation.

Let a market economy sort the development and allocation of resources.
