One hopes that the . has not and would not go to such extremes again But we are currently seeing it happen with respect to Muslims who are, apparently, not deserving of the same rights as other people according to Trump and some of his followers. We saw it with respect to Mexicans during Trump's campaign, where he accused them of being criminals and rapists. Both groups now are under siege, Mexicans and other undocumented immigrants fearing deportation daily, and Muslims increasingly being attacked and even killed for their relgious beliefs.
On the average poor countries undergo a percent increase in population each year; rich countries, about percent. Only rich countries have anything in the way of food reserves set aside, and even they do not have as much as they should. Poor countries have none. If poor countries received no food from the outside, the rate of their population growth would be periodically checked by crop failures and famines. But if they can always draw on a world food bank in time of need, their population can continue to grow unchecked, and so will their "need" for aid. In the short run, a world food bank may diminish that need, but in the long run it actually increases the need without limit.
