Avram in MD,
The teretz is that all other things being equal, a person who learns Torah more is better than a person who learns Torah less.
I agree; however, it is fundamentally impossible for two separate people to have “all other things” be equal. So this answer is functionally meaningless.
The point certainly does have meaning once you understand the underlying message. Namely that learning more Torah is better than learning less Torah. So the act of being in Kollel and learning seven hours a day is better than working seven hours a day and learning one hour a day. So for an individual capable of it, it certainly is better to be in Kollel and learn more Torah than to work and learn less Torah.
