Yes, I know you can. Just as you can make money making music. The important word here is "can". You are not however entitled to it. A lucky few gets paid but that's an extreme privilege you shouldn't take for granted.

The difference with development is that no-one questions the business model. You code and get paid for it while music is a completely different story. Before I became a professional developer I coded for fun and was happy with that. If the market would be like music (where 99% of artists cannot make a living out of it) then yes, I would say exactly that.
