Here are some excerpts:
Rabbi B: ...However, there is no question in my mind that you are NOT doing that which HaShem wants you to do. He didn't give us the Torah so that a person would spend 40 prime years of his life learning one hour a day!!
Rabbi B: "Tainted"? Why tainted? However, you cannot honestly believe that this is what HaShem had in mind when he gave us the Torah.
Come on now!
Rabbi B: Anyone who really believes that he is a true Oved HaShem when he spends only one hour a day in the BM is really very very confused.
Now, I'm certainly no scholar, and I'm certainly no tzaddik. But what I can do is read... I can open up a chumash and take a look at several sections. Specifically, the Torah gives us all sorts of laws that apply to farmers. Why? If everyone is to spend all of our time learning, then why give us laws that apply to farmers? There are laws that delineate how one is to behave in business dealings. Why? Who is going to go into business? There are laws covering all sorts of professional and personal activities that shouldn't be necessary if we are expected to learn all day long.
Many of our gedolim throughout the years supported themselves by taking jobs. Were they not doing what God expected of them? My son's Rebbe (fifth grade) doesn't learn as he could for several hours a day because he's busy teaching elementary gemara and chumash. If he learned full time, I have no doubt that he could answer many more difficult ktzosim (see the original exchange) than he can teaching little kids. Is he not living up to his potential? Is he a disappointment in God's eyes as well?
Ultimately, however, I think that the there is a much more basic point to make here. The point is that we, as people, live in this world. God created us as we are, with our physical needs for food, clothing and shelter. God, in His wisdom, decreed that man must work for his living. God provides for us, but only indirectly. It's with His help and guidance that I earn a living, but, in the end, I still have to show up at work every day. I suppose that if I didn't want to work and God wanted me to have a living, He could cause a winning lottery ticket to show up in my wallet one day... but generally, He does not work like that. The way of the world is that one needs to earn a living (or be supported by others).
To my knowledge, there are very few cases where people have been miraculously sustained and therefore free to pursue Torah learning with absolutely no encumbrances. The most famous example was probably the Generation in the Wilderness. God provided manna from heaven, their clothing did not wear out and their shoes did not decay. As such most, if not all, of the Jews were able to pursue learning full-time. Once that ended (upon the entry into Eretz Yisroel), did people generally learn full time? No - they became farmers, vintners, metalsmithes, scribes and any of the dozens of other occupations that were needed to create a functioning nation. Were there people who learned full time? Certainly - but certainly it wasn't a majority or even a significant minority.
Another famous example concerns Rabbi Shimon bar Yochai and his son Rabbi Elazar, who were sustained by God in a cave for over a dozen years while in hiding from the Roman authorities. During the dozen years that they were in hiding, they did nothing but learn, as God provided for their needs miraculously. Indeed, what happened upon their exit from the cave? Their world-view was so out of step with everyone else's that God had to remind them that working for a living was not wrong or evil. In other words, God explicitly told them that man was meant to work - and sent them back to their cave for another year until they could learn that lesson.
So, what does it all boil down to? When Rabbi B says that a working person is "NOT doing what HaShem wants him to," he is clearly wrong. After all, if God didn't want us to earn a living, why did he send R. Shimon and his son back to the cave? He should have instructed them to convince all of K'lal Yisroel to put down their tools and learn all day. But that's not what He did.
Does this mean that full-time learning is wrong and contrary to God's will? No, I don't believe it is. The Jewish nation has need of professionals in every time period -- whether they be farmers and vintners in the ancient agragiran society of Israel of old, or doctors, lawyers and computer professionals in today's world. But they also need people who are experts in Torah -- in every age. We need people who learn full-time so that we can have poskim and rabbis and teachers. But we can't be a nation of exclusively learners. And those who work full-time and learn when they are not working are doing just as much to help further society.
If God truly wanted all the Jews to learn Torah full-time and not engage in professional activities, then He'd provide for us in the manner that He did in the Wilderness. The fact that He does not, and that he gave laws regarding our professional conduct, clearly indicates that it is permitted and worthy for us to enter into such activities.
