Things humans don't need

I was asked this odd question that left me thinking because of how many answers I got in less than a minute. Anyways the question was form the game of things and it was, Things that humans don't need anymore? There are many things humans don't need like technology, desserts, vacations etc. but they do think they need them to survive and that they have the rights to do and deserve anything, but to be honest they used to be my meal so I needed them back then when I used to be a vampire but they still made great puppets because to be honest its not what they need is how I need them they are just such simple things I can use to do my bidding, but when I was one all they did to me was punish me betray me and treat me like crap so to be real I enjoy having them under my control but I would rather be dead than to return to being one of those powerless mortals. Now I get to punish those who use their very short life the do wrong because they don't need anything.
