FYI, there is no shortage of food in the world. The problem of starvation is a problem of distribution. In fact the number of starving people is equal to the number of overweight people. Also a majority of the grain grown in the US is fed to livestock, i.e. wasted. Following the precipe to love thy neighbor need not involve mortgaging anything. All that would be required for us Christians to do would be to reduce our food consumption to a healthy, normal amount and send the rest overseas.
Send it overseas for what? free? If we implemented your idea, the moment Americans stopped scarfing down three big-macs a day, half of the food industry would go bankrupt. In a very short time the industry would shrink adjusting to the change in demand.
Why the hell should I pay more taxes for starving Africans who chased and murdered the white farmers out of their counties?
