As a society we were dependent on each others but when we handed over all our personal responsibilities to the governments, everything changed. We became slave because after paying taxes we think that the government will provide everything for us. Now for water supply, food, roads, power, security everything comes from the governments or government approved private companies. This has made us handicap. We have lost our capacity to survive in worst cases. We need to study these primitive technologies so that we may survive in the worst case scenario.
