Most dogs and many people harbor parasites within their body. These can be life threatening if not adequately treated. The parasite uses its host’s resources and gives nothing in return.
Likewise a person who habitually relies on others and gives nothing in return is a parasite by definition. I believe we have far too many of these people in our society that have been enabled by our social programs, which were initially designed to help those in need. Today the programs have been abused to a level that has lead to entitlement. This phenomenon, like parasites, needs proper treatment to save its host (our society). What can we do?
