A military is an essential part of an advanced nation such as the USA. It is one of the few things that is spoken of in our constitution. A military is usually required because it defends the interests of a country or sovereignty of a nation. It can also be used for other purposes, as history teaches us. Military might may also be used to enforce the will of a small minority onto a larger majority, weed out dissenters, or wage war on another nation. Sometimes just the threat of a war can be a powerful deterrent and this threat is often used in diplomacy. A national defence is one of many expenses a nation has and no other country spends more on their military than the United States.
The US has also spent over one trillion dollars on the social security program in 2015. It's one of the most expensive social programs. We spent over 950 billion on the Medicaid program. The Supplemental Nutrition Assistance Program received seventy four billion in 2014. Private Welfare spending was over one trillion dollars. There are a multitude of other social programs but listing them all is not the point of this article.
Almost all social programs serve the purpose of providing food, education, housing, shelter, healthcare or just cold hard cash to it's recipients. These give-aways are controversial since they encourage people to qualify to receive the benefits of each program and discourage people from working to take care of themselves. They are one of the main reasons we have so much taken from our pay checks and one of the main causes of low workforce participation and high unemployment.
We spend close to six hundred billion dollars on the Pentagon and military programs. Our armed forces provide it's volunteers with food, education, housing, shelter, healthcare or just cold hard cash but it's not a socialist program. Our military is much like a dictatorship. They don't practice democracy; they preserve it. Our military can also defend the interests of our country or sovereignty of another nation.
