Please read the thread (I know, it is long).
Stallman proposes "a solid approach on how to change things": write free
software. As it was discussed in length in this thread, many people do make a
living in this way. In fact, free software related businesses are thriving at
a tremendous pace while the rest of the occidental economy is suffering.
Stallman himself started, alone, to implement this practical solution in
1984. You cannot deny that he has largely succeeded since, today, you can
work with a 100% free operating system... or do *you* suffer from a
"real-world perception disorder"?
As for getting motivated by money, ask quidam (Trisquel's leader) whether he
believes he will make more money with Trisquel than with any other job
exploiting his technical skills. I see a difference between "making a living"
and "getting motivated by money".
