>>Also, the numbers balance doesnt work out. When its a small percentage of people learning full time, communities can band together and make sure those learning have a good lifestyle. But when the ratio is skewed, how can the community afford it?<<
The numbers aren’t skewed, we are. Yissachar/Zevulum was 50-50. It isn’t 1000 people giving change to support 1 person. It is skewed because we have convinced ourselves that luxuries are really necessities.
By the way, please show me where one can only learn if someone supports them. If you are claiming that people learning have a sense of entitlement towards other people’s money, or that they don’t truly have bitachon in Hashem, then that is a completely different conversation than the one we are having (and one where our views could very well be identical).
