We take Private education as a need
Because it is.
Kollel shouldn’t be mainstream!! It should be for a few, exceptional people who are the next Gedolei Hador, as it’s been for the past 2000 years.
You’re in disagreement with many of those very same Gedolei Hador.
The same way 99% of the readers of this site probably agree that a yeshiva education is not a luxury but a necessity, many of our gedolim have, with their superior wisdom, determined that we need more than a just a few yechidim devoting some years to full time learning, in order for klal Yisroel to function properly (spiritually).
