How would the US really react to a instant stoppage of Fossil Fuels

In class today we watched the video on how Cuba handled themselves when their energy resources got cut off with no notice. The discussion that followed lead us to our opinions and ideals as to what we would do as a country if this happened in the US. Some feel that we would come together as one and be OK and make adjustments like the Cubans did. Others felt that we wouldn't. I believe that there are many out there that would want to unite for the good of all but over all I don't see this happening. America is not what it was in the 1970's oil shortage. This country is very large and populated. Its a violent society as a whole with fire arms easily and readily available. Violent crimes are committed every second of every day and for what, to steal a car, jacket, sneakers, wallet etc..... Just imagine if food which is for the most part very available to us now was not. Would you be thinking of your neighbor if you where hungry and didn't know when the next meal was coming. I am sure I am one of the few if only class member with children, let me tell you feeding my kids would make me take drastic measures. This is just a point that I wanted to put out there. We have evolved into a me first materialistic society that combined with its size, social structure and geography would be very hard to emulate what the Cubans did. Also it would take the govt. to instantly devalue money. If money was not worth as much as it is in our society people would be more inclined to farm or just grow there own food and be more helping toward others. Basically we need to change our cultural priorities of today.
The last thing I would like to comment on was the talk at the end of class how maybe the University should offer courses on things like basic cooking, gardening, some "handyman" type things around the home, care etc. I personally feel that these things should have been already learned by college aged students. These things for years where taught by families and passed on from generation to generation. Its not a college course, its a life course that I believe is our parents and grandparents responsibility to teach. However in today's society there are to many broken homes (which is not really an excuse) cases of children having children and an emphasis people wanting so much but not wanting to get there hands dirty earning it which has eroded how these lesions have been learned form family. It starts and ends at home with the family. Basic life skills and knowledge is not a college course.....!!
