when a person does a siyim he talks about 2 groups of people, yoshvei koranos and yoshvei bes medrish. seemingly, both of these groups basically sit all day. one group sits in the beis medrish and the other playing cards. yet he says anu ameilim veheim ameilim and rutzim veheym rutzim. seems wrong to say amilim or rutzim about either group. seems like neither group is rutzim or ameilim. furthermore, almost all of humankind does not fall into either category. most people dont sit around all day playing cards or in the beis medrish. (i think someone pointed that out once in one of these topics) most people get up in the morning and go to work and in their free time go to either beis medrish or to the theaters and coffee houses. and even people who go to beis medrish sometimes go to a coffee house and probably the people who go to coffee houses sometimes go to a beis medrish.
i think what it means is that lucky for us that our focus in life is to learn torah. we work in order to be able to live jewish lives which should primarily involve limud torah. the yoshvei beis do all of their amuelus and ritza in order to learn and live jewish lives. the yoshvie keronos do the same exact ameilus and ritza side by side with the yoshvei beis medrish in their offices and in the field but because they do it in order to “get to the weekend and vacations” they are yoshvei keronos and the other guy sitting next to him in the office does it in order to live a jewish life and to be able to get to the beis medrish. it all depends in the focus of the person’s life.
so the learner/earner is a yoishev beis medrish and the disney land /earner is a yoishev keronos.
