RCs are this network's fees. We have so little demand (or such good scaling) that those fees currently round to zero. The system we have is good.
We can't start paying more witnesses until we have more stability and witnesses are getting paid an obscene amount. Instead of a 10 cent floor it would need to be something like $1 before we can talk about that. Again, paying more witnesses increases our decentralization, thereby making our scaling worse.
