I normally like to watch how things turn out with your arguments Billy but this time I can't resist.
First of all, Welfare, as your intial topic was refering to, is the program which offers financial assistance to people who do not have the means to support themselves. Financial aid is a program that gives money to students who are going to college based on need--meaning you do not earn enough money to financially pay for college and you get funds--it generally isn't much above tuition and books really (if you are lucky).
Military service is a job. The people who serve in the military are paid for work they have performed. Just because you do not think it is work doens't mean that it not work and therefore welfare. By your definition anybody with a job is on welfare. Of course, you could argue that without you owning the means of production yourself, you are basically at the welfare of someone else--but that is more a philisophical debate. Factually, those who work are pulling salaries for work performed and not considered to be on welfare.
However, people on welfare and in the military receive public funds. That is the extent of the similiarities of how they receive monies though.
I think your argument is poorly constructed in the "military people are on welfare".
To the topic of drug testing welfare recipients--the counter of that argument is: Why stop at the people receiving the benefit? If it is public money being used and drugs are illegal--why aren't we also calling for the testing of the people who profit from those who spend the benefits? Why no call to arms to drug test the landlords? The supermarkets? Wal-Mart? Shouldn't we also ensure that those who make a profit from public welfare funds also be drug free? The CEO's? The supervisors and managers? Why wouldn't we want to ensure that we are not supporting their drug habits and bad lifestyles?
See...that is where you see the true disparity in how we view the disenfranchised and the poor. Did that argument never cross your mind to think of it in that way? It is always about money and power. Those with the money and power exercise it against those who don't have it to keep them arguing amongst themselves rather than looking at them.
