Although you bring up a valid point, I must contest your statement, “there is no excuse to not to go to school whether you are in Yeshiva…”.
It has been my experience that many Gedolim would not agree to Bachrim and Kolelite going to College on the side during Yeshiva as a general rule. Of course, there are exceptions. When you make such a bold statement as you did you are basically saying that you are wiser than they are. Do you feel that you understand the full picture better than them? I hope not.
