Reb Always_Ask_Questions,
Those numbers are totally irrelevant. Even if the Charedi population pays less taxes then the rest of the population, that does not mean the taxes they pay don’t cover the governments expenses for them by a significant margin.
Let’s also remember that like in America, there are many things the government pays for that are of little or no benefit to the frum population. In public schools in Israel (mamlachti), both religious and irreligious, tuition is completely covered by the government. In those schools the teachers are also generally paid (much) higher salaries, and a lot of government money goes towards fancy equipment and facilities. The government does also help with tuition in private schools, but not nearly to the same extent. There is also a tremendous amount of government money that goes towards Universities, stadiums, and many other cultural expenditures, and liberal research groups that are of benefit to some parts of the population but not others.
This is why we are fighting for tuition vouchers in america; so that our tax money doesn’t exclusively go toward kids learning about the 8 different genders and affirmative action, and not towards the schooling for the religious tax paying communties.
My sister-in-law’s research lab (which was actually a useful one) paid for all-expenses-paid trips to different exotic countries for the researchers (including her) to basically do nothing because the head of the lab felt it would be a “great cultural experience”.
So feel free to try to put together the numbers, but due to all the silly things governments spend money on, for many of which the charedi population does not contribute to the expense or benefit from whatsoever, I would think it’s highly doubtful that charedi society is costing more than their economic contributions.
