> Bread salt and water. If you have that, you have parnasah. The Rambam writes that a typical Baal Habayis works 3 hours a day and learns 8 hours a day.
I absolutely agree here. We can live now reasonable comparing with previous generations and learn whole day with one change of clothes and no indoor plumbing.
A more realistic solution would be to follow Rambam is to work 3 hours a day professionally and learn the rest of the time including teaching your own kids.
