If I were President of this Country, would changes would I make?

If I were President, I would make sure that we could all have free food. I am picturing walking down the aisle of grocery stores and each person could take as much of whatever they want and/or needed for themselves and their families. People who work in factories to produce food and the farmers who bring our crops to the stores would be working for free because they would love being able to have a part in helping out other people. I would also make everyone have free medical coverage. It would not cost for anyone to go to the doctors, get perscriptions, go to the hospital, etc. With having severe allergies and always being sick it would be great if I did not have to spend $250 on a hospital visit or the $700 on the prescription that I was given for having an allergy attack. It is not cheap and I am not sure if people who cannot afford this can even survive. Are countries who have free medical care better off and do their people live longer??
