A labor economist has written a new book subjecting Jewish identity to a formal cost-benefit analysis. Attempting to sort through the decisions made by American Jews about synagogue membership or whether to send their children to day school, she proceeds on the theory that such abstractions as community and religion are themselves “goods” (like toasters and televisions). She even applies the same measurement to make sense of the resurgence of Orthodoxy. Steven I. Weiss writes:

Carmel Chiswick shows how this view can alter the equation [faced by parents] when looking at the two major options for preparing a child for a Jewish life and a bar or bat mitzvah. Jewish day school is the full-time, dual-curriculum option available at Jewish private schools; by contrast, “Hebrew school” is the term used to describe a much more limited program of study, often on Sundays and a few weekdays as an after-school program at a local synagogue. Chiswick assumes that the several hours of extra time required to shuttle one’s child back and forth to Hebrew school instead of enrolling the child at a full-time day school can represent a time cost of $18,000 per year for a $200-an-hour lawyer. Suddenly, the combination of public school and Hebrew school rather than day school doesn’t seem like such a bargain.

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
