The State of commisions

In this ever changing market what direction should the commision structures of the old era be headed? With brokers stuck in expensive leases and large overhead what happens to the agent? I think in this current world we live in we all must make concessions brokers/owner and agents to find a miidle ground to make the business work. There are sacrifices neccesary on both sides to make it work. Let's remember our sellers who we ask to make concessions all the time, isnt this the same thing?
