From my own sente of view , I think this sentence is very positive and thought provoking. I belive this sentence mean every one who are working in the bottom of the Society should not be sad , so that they can use their time on working hard instead of crying. There is also a common saying that is very similar “success are prepared for the one who are prepared ”
I think both sentence say that people should work hard and never think in a decadence way , it’s much better to think in a positive way no matter you are in trouble or no.
