The problem then is that some people do not have the right pieces of paper
(money) to buy food. If these people do not get food through charitable means
they become losers under the current rules of the game of life (death through starvation). Changing the rules (politics) has never stopped this problem, but just made different winners and losers. That is why Buckminster Fuller http://220.127.116.11/ sought a solution through a game where political solutions to world tangible need shortages were disallowed. There are solutions through proficient use of current resources to allot of human problems (new technologies are need to solve the rest).
The solution for 'proficient use of current resources' is the free market. Any country where you can find widespread malnutrition you will find excessive state control of the economy, and manipulation of the same to repress some dissident portion of the population.
