An OSS living

[joshua rh comcast net]

Hello,
         I recently had a spirited debate with a friend about proprietary software.  His main thing about it was: it's where we make our money as developers.  My arguments were: better software,  more potential, more compatibility, and doing what you like to do.  Most of his questions we're something to the effect of this: How can you make a living when your software is free?  I too would like to know if any of you out there make a good living developing open source software, it seems like what I want to do, but I don't quite know where I would make my money (I know Canonical does support for Ubuntu) developing open source software.
