I have no idea why you think any of these chatzeros are neglectful of aniyim. That’s an absurd and baseless accusation.
Do you really think today’s society is poorer than the society the Rozhiner Rebbes lived in? Punkt farkert. We live in possibly the wealthiest era since brias olam, and if there’s not enough money to support aniyim, it’s not because it’s wasted elsewhere, it’s because it’s not given to tzedaka.
