1. Israel and the Middle East will be affected more than the United States, since they import foodstuffs from Russia and Ukraine. While other regions can replace what is lost, it will cost more. And since markets are globalized, prices will rise everywhere. Only Ukraine itself will have serious shortages, but these will be made up for with foreign assistance. Farmers and shippers in regions far removed from the war zone will be the big winners.
2. “Profiteers” are everyone. Who has a job where they asked for a lower salary since they refuse to be a profiteer? What tuition committee would be sympathetic to someone who insists on working as a volunteer (and relying a tsadakah) rather than taking a paying job?
