Dear Grateful,
If a girl insists on marrying a long time learner, she should go out with boys that are learning now and discuss it with them. If she wants to get no dates and be an older single, she should talk to shadchanim about who or what is a long term learner.
A brilliant person can be cruel. A talmid Chochom by definition is referring only to a person that is not cruel.
Your questions have nothing to do with long term learners. At best it will identify if the boy is having a good zman. Long term learners, will learn regardless of income. Long term kollel is a whole different story.
