Which leads to a higher standard of living, dependence on others or complete self-sufficiency? Before you answer the question, consider which approach better represents your life. Do you have a job and pay all your own bills, or do you live at home with your parents while they foot the bill for your upkeep? If you are on your own, you most likely consider yourself to be self-sufficient. If you are still living at home with your parents, you probably consider yourself to be somewhat dependent. The truth, however, is, whether you are on your own or living at home, you are highly dependent on others for the food you eat, the clothes you wear, and the roof over your head. In order for you to get what you need and want and enjoy a higher standard of living, then you must trade with others.
