nolongersingle – for #1, Both Meretz & Yesh (Ain) Atid want to lift and help all Israelis (granted by their definition of “help”), Charaidim included. A more similar comparison would be to the Arab parties, who are solely interested in helping the Palestinian cause (as compared to the Limmud Hatorah cause, lehavdil).
As for #2, you are 100% correct. That is why the OP’s assumption is wrong. He assumes that the main issue is the lack of jobs and poverty. A real Israeli Charaidi would probably say the biggest issue is that there isn’t enough Limud HaTorah.
So yes, the Charaidim are guilty of not supporting the “Israeli” cause, but Hashem and his Torah. That is not something they are ashamed of. Should they be?
