The economic principle I examined was Scarcity, people choose. All choices have an opportunity cost. There are many situations where this economic principle can be applied to the real world. For instance, while studying the federal budget and military expenses I found many examples of this principle. First, the United states spends a significant amount of money on the military. For instance in 2015. Military spending totaled $598.49 Billion which was 54% of the discretionary budget.  Second,Increasing the military will take money away from other useful national organisations like, the IRS by lowering their budget This demonstrates that Due to the scarcity of tax dollars we must choose wise how to spend the money because all choices have opportunity cost. Third,The US spends the most money on the military than any country in the world. If you were to line up the six militaries with the largest budget the US will still have a bigger budget. This means that some critical programs like education and science  can receive more funding by cutting a little money from the military without denting their budget .Overall, you can see that the US spends a ludicrous amount of taxpayer money on the military, Although without the military many of us if not all would live in fear of global chaos, but is there a possibility the government can take a few 100 million dollars from the military budget and into place where we can see the youth and future of america grow strong.
