1. you didn't create $1000/mo. You did something that caused the (temporary) transfer of control over $1000/mo of economic resources into your hands. That means that what you did was not judged as useless by everyone else in the society where you live - and that's good!

But the value of your software is utterly contingent on the full context of where you live. As many have noted, there are many highly paid jobs in (say) the USA that would simply have no value if you attempted to perform them in, say, Sudan (especially right now). So that $1000/mo is predicated on the work that others have done to create a context where your work actually has some value. Take that context away (or destroy it), and your work is close to worthless. So, where does the value in your work actually come from? No doubt some comes from you ... but how much is a lot harder to define.

2. I never said anything about fair.

3. I have no idea what your $1/hr example is intended to demonstrate.
