why do people feel the need to buy expensive cable

I have tried expensive cables and one's moderately priced. I would say there were some differences but I can't actually say the expensive cables were better. IMHO I believe a lot of people buy expensive cables because they don't actual trust their ears and are afraid of making a mistake. They figure the expensive cables are better for the fact they cost more. If you have a difference of opinion or share the same thoughts, I would like to hear about it.
these discussions should just stop. Cables make major difference is systems depending the system itself .. higher resolution systems can benefit from higher end cables. I have heard the change countless times when I was in the business years ago. So these were not cables I bought so I needed to hear a difference. When the know it all post comes in "snake oil etc etc" "audiofools" .. my first thought it they do not really listen listen to their system

>>>>I suppose you could say it’s healthy to have a difference of opinion or have some kind of legitimate counter-argument from skeptics but I’m afraid these are not real debates. In fact many if these threads are started as a joke. Isn’t it obvious?  The “Skeptics” are almost always little scamps who are in it strictly for the laughs and who enjoy teasing the audiophiles. It’s really as simple as that. Like cats teasing a dog. Isn’t it obvious? 😳
