It isn’t necessarily that Rabbi Shafier is expounding any particular point of direction. His hashkofos clearly follow those of his yeshiva, RSA, and it’s blessed Rosh Yeshiva zt”l.
The Shmuz was originally started to provide a yeshivish type learning environment for yeshiva bochurim who are now part of the workforce. And I will not elaborate on whether or not yeshiva guys should be working or not, because that point is irrevelant here.
The shiurim are excellent, very listenable. My personal favorite, and I certainly haven’t listened to all of them, is the one about genevah.
