You go ahead and wait in line to feed those you love. I'll be at home, safe and feeding my family without having to depend on others.
Additional sources of income are fine, but why not do both, just in case?
Oh puh leaze. I live in Utah. I live an hour away from town. Except for milk and fresh fruit we start getting nervous if we have less than a years worth of food stocked up. We have a greenhouse and my wife loves to garden. I have access to a spring and the materials and know how to go off the grid for power and heat. Having said that, I am not self sufficient. I don't really think it is possible to be self sufficient.
My point is that preparing for a Mad Max scenario is financially stupid. Buying bulk food items that you like to eat, on sale, is smart. Buying guns and ammo before you are out of debt is stupid. Investing in a foreign company to get dividends in time of a crises is smart.
Predicting the future is impossible. Planning for the future is smart.
