But these very people don't understand that they are currently enjoying one abundance right now: Free air.
The question is: How many things can we make as abundant as air?
OSS is there in fact. I would argue that electricity is next, then education (Khan Academy and the like), and one day fresh clean water.
We just have to keep knocking down one scarce resource at a time. The same way we don't take a single leap straight up the staircase, but instead take small steps to get to the top.
