I've not down voted you. It's a matter of survival. I sleep on the ground under a tree until I get a sleeping bag, and then maybe a cot. Before I buy a nice soft comfy mattress, I need a safe, secure structure for it.

Think of the liberal arts in this way. Once we have what we must have to survive, then we can go after the things we want as humans to enrich our lives and those around us. I love art and English majors... I just can't enjoy Rembrandt when I need a place to live or clean water to drink or a sewage system, etc :)
