Why should my hard earned money go to those less fortunate?

[Tonus]

I'll never understand why people are okay with wasting money on drug screening for those one welfare.

Because of the assumption that SteelCurtain referred to-- that most people on some form of assistance are drug abusers.  It's easy to fall into the trap of thinking that the system is being defrauded by almost all of the recipients.  Most people who are receiving welfare of some kind are aware of the stigma and aren't going to let anyone know about it, so the ones that stand out are the ones gaming the system in some way.  It's not like the local news media is going to run stories on the people who use it as it was intended.  They're going to cover the ones that milk the system illegally.  And then there are the local drug addicts that people accuse of being on welfare even if they aren't, because they fit the stereotype.

There is waste and fraud and it's difficult to root it out, but the good that is done by welfare and similar programs is something that I wish could be quantified and also demonstrated with examples, so that people would understand how important they are.  There's fraud and waste in many industries that we're willing to accept because they provide useful services (auto insurance is a good example).  No one's demanding that we do away with auto insurance and telling people to "just drive better."
