Assuming that we're treating labour as a market, then the most obvious way to raise wages is to restrict supply, or at least restrict the terms on which that supply is available. That's unionisation (if done via "private" means) or minimum wage and conditions laws (if done via "public" means).
I guess there's also the possibility of consumer pressure reducing demand for goods produced except on decent terms, but that seems less likely to be effective than some more direct way of tackling the problem as far as wages are concerned. But it probably can be effective for ensuring direct support of self-employed producers. This means RPGers paying good prices for small games. Which probably does collide with some other features of the world of RPGing (ie most people play a big game whose creators are employees or contractors).
The other solution, as has been mentioned, is to bypass the labour market altogether in ensuring minimum standards of living. But that's not a distinctively RPG-oriented approach!
