But the concept of subordinating your individual interest is fundamental to the success of any nation.
One can surely frame it that way. The founding fathers certainly did make supreme personal sacrifices for the young nation. They expressed that sentiment by their actions. However, I don't recall them using language like this. This is the way that socialists speak. In fact, it is the way that Stalin, Hitler and Mao frequently spoke. I think the spirit of the founders tells us that we all should be ready to make personal sacrifices for our personal liberty and that of our children.
