Food prices will keep going up because of the increased demand due to population increases. The government stockpiles commodities. So, I do not think food prices will ever consume a major portion of our income such as the case in 3rd world countries. I am very skeptical of the doom and gloomers. Living in a hurricane prone area, I have enough food to last me a month or two in two different locations.
Since gold and silver has been used as money for many, many years, I view having some as an insurance policy. In case of an emergency, it just might come in handy. Those that are anti-gold do not have any. In an emergency, the money you have in a bank or your credit card will be worthless if there is no electricity.
