GotAPoint, I hear your bitterness and I am familiar with all the issue you are raising from R Wissmandel to Sephardim. At some point, worked with my kid on an essay describing how Begin looked differently at Sephardim addressing them as heirs of Rambam, rather than poor cousins. Another example of ideological bias in Zionist development was emphasis on kibutzim pre WW2 v. development of Tel Aviv manufacturing. Sochnut inserted itself between donors and recipients who wanted to support T-A as manufacturing was providing additional jobs and thus a place for immigrants to come, while kibutzim were providing land and otherwise was a bottomless pit. I saw research computing how many would have come pre-war from Europe and did not, sad…
Still, I think your recounting of Haredi contributions is way biased. Again, I understand pretty much where this coming from and is passed along for several generations already. For one, there is no reshus to disregard your obligations just because you think you were cheated somewhere else. See Rav Huna with his spoiled wine who did not want to pay workers who already “helped themselves”, was rebutted by other chachamim and deserved a miracle for teshuvah, either open (vinegar -> wine) or hidden (vinegar price up).
We in America also pay taxes, while murdering less, paying for schools we do not use, and sometimes have to move to a different neighborhood when government policies lead to disaster. Most of us do not see this as a reason to cheat or hate the country. So, I surmise, your bitterness is more due to the fact that these are specifically Jews who are in power and do think that you disagree with. It is, of course, understandable. The closer we are, the more we expect and the more we react to problems. So, you just need to acknowledge that.
