Mz. Tzippi:
How much does one make in Klei Kodesh?
Hishtadlus doesn’t work that you will make enough to pay full tuition if the job does not normally allow one to do so, except when the RBS”H makes a specific exception, which in that case playing LOTTO will do the same Hishtadlus. My point is that for Klei Kodesh either expenses could be cut or additional hishtadlus put in, so they have two choices, vs. the working family which only has one choice. Klei Kodesh are also expected to cut expenses, since they are willing to sacrifice more for Torah than in the case of the original letterwriter.
(If you have found a Klei Kodesh job that pays full tuition for a large family, please tell me so that I could become Gavra_in_Klei_Kodesh)
