One good way to start to to focus more on developing and energizing your pledge class. Get them as involved as possible, and make them psyched about improving the organization. When they are new initiates, brainstorm with them on how to improve things.

If you get new guys energized enough, they will step up and take the reins, especially if the older guys are apathetic. If alot of the worst guys are seniors, then the problem might quickly go away when the apathetic people graduate while a new generation of motivated guys step in.

You aren't very likely to change the mindset of the lazy people. You're best bet is to motivate the next generation while making sure the lazy actives don't get in the way of change. That might mean removing brothers if they are dragging the chapter down, or it might mean encouraging newer guys to take control of things and see if the lazy people fall into the background and not interfere.
