In a world that revolves around money....NO! you can not live without it at all.
If you have none, then you're likely to be spending the remainder of your life out in the streets, not showering, scrounging for food wherever possible(garbage cans, back of restaurants and stealing from supermarkets) and not sure what you're going to do the NEXT day.
Approximately 12.5% of the population is homeless already.
Not to mention, there are a TOTAL of 700,000 beds in shelters, missions and other locations, which is pathetic considering there is about 40 Million homeless to help?
money gets you things to survive. i.e. food and a glass of water.. We're just brain washed from an early age on for the things we should need and want. I.e. Why did a cell phone become a necessity? No one had one 15 years ago? Are times changing that we cannot survive with out "things"? I think "things" is what money is for. To enjoy life, you don't need money, you need friends, family to live a content life. Just my opinion.
