As for the part that Chareidim pay no taxes.
That’s impossible there’s an 18% VAT tax in ISreal how can you pay not taxe’s?
Plus 45% of Chareidi men end up working as do the majority of Chareidi women.
Add to that the Tourisim industry in Isreal in which Chareidim play an outsized role. (El-Al’s most profitable route by far is JFK-Tel Aviv ever checked who goes on that flight?)
