Personally, I feel standards are falling. O-sensi must be rolling (doing ukemi) in his grave.
Put all the talk aside for a minute and look at classes with an open mind. Money must be the chief motivator, as there are so many poor, weak students out there. Put the pressure on and you know they'll walk.
Try changing your teaching methods drastically (for a few classes) and see how people react. Just have everyone run for an entire class. Or meditate. Or whatever. Try randori (for non-Tomiki styles) or whatever will shake up the class. Take the class outside the dojo.
Grade less, train more!
I think standards are much lower than in the past (or I hope so).
