“If the world worked on a barter system, how would you fare? Would you have services to barter? Would you be successful, or would you struggle?”
I believe I would fare well under a barter system. I have experience teaching and working with children. I also enjoy cooking, especially making sweets. I would also enjoy the interaction that a barter system fosters. You mow my lawn, cut back the brush then I give your children piano lessons. You cut and color my hair, I bring you bread and cookies. We form a community with each other more than if we just exchange cash, checks, or plastic.
