Parasites

"One may of course live in a country parasitically accepting all the benefits for which others have sacrificed--both in the past and in the present--while rejecting any notion of being obliged to do the same."



Thomas Sowell, "Intellectuals and Society"

parasite is defined as: "One who habitually takes advantage of the generosity of others without making any useful return."

American Heritage Dictionary

It would truly be a wasted life, if, at the end of that life all anyone can say is, "he/she took up space for a while."
