Igros Moshe on Kollel Income

Furthermore it is my opinion that those "Mischassidim" from the side of the Rambam's opinion is advice from the yetzer hara in order that they interrupt their learning and engage in labor and commerce and the like until ultimately they forget even the little which they already learned and aren't relaxed enough to fix even a small amount of time for learning Torah.

Since if the Rishonim were like melachim and said that it was not possible to engage in Torah and become wise in it while engaged in labor to sustain themselves by the work of their hands, certainly in our generation...........it is not possible for anyone to boast that he is able to engage in labor and become wise in Torah. Therefore do not let the thought arise in your mind that advice of the yetzer hara that with a stipend from learning in Kollel, being a Rabbi, teacher of Torah, or Rosh Yeshiva there is any sort of sin or lack of middas Chassidus, since it is only to instigate one into separating from the Torah.
