mamashtakeh did a nice analysis. The only thing that I think is missing from it is the first thing that comes out of earnings – Ma’aser gelt.
If you separate Ma’aser and give some of it to Yeshivos, you ARE supporting Torah. Sorry if anyone thinks that the average Yankel has to take on the oil parnossa of an entire Kollel family – that is just not possible. Maybe if the average kollel family wanted to take room and board with an average working family something could be worked out – but to pay for 2 sets of houses, cars, tuitions, utilities, clothings, etc? Forget it. Anyone who even suggests it had better get their prescription checked for hallucinogens.
