Why couldn’t Tony save Beansie from Richie Aprile?

After Richie roughs up Beansie for the first time, Tony clearly tells Richie Aprile in the mall that Beansie is a good earner and Richie must backoff. If Beansie was earning for Tony, then why didn’t he protect him since it directly affected his bottomline. Richie’s feelings for Beansie indeed made things financially unfeasible for Tony.
