It is a cold hard fact that immigrants, legal or otherwise staff the American food industry. US agriculture is subsidized by government cash handouts, which are then used to pay the wages of border jumpers who export the cash to Mexico where the money is then returned back to the United States via cartel of illegal firearms.
Ukraine, Libya, and Syria are in ruins because of USA/CIA intervention.
Do rich kids really ever enlist? Unless they have a dream of working in politics later on? The infantry in the Marines and Army is overwhelmingly Caucasian, with a sprinkle of Mexican for the most part. Support jobs in the rear are by and large staffed with African Americans. For one reason or another, that is the way it is. With small exceptions along the way.
The American people have ADD when it comes to war and the stomach for war. What always makes me laugh it liberals that chant "love wins" as they blog from Starbucks. And are totally oblivious to the brown women and children the President kills with drone attacks in the name of freedom.
