whose life is limited by just eating, drinking and going to toilet
I would say - in our world, the life is not limited by that. Life consists of that. Many people having that, are already lucky. I mean, if you have something to eat, to drink and to have a roof over your head where you could safely make a pee, that's already nice.
Each opinion on our forums is worth. In your opinion, you miss one thing: people are
different. It is
important where you come from, how much do you earn, how do you look and so on. It is
. The other difficulty here, is to determine, what exactly is more
important and what is less
important. It's not about "human occupancy", it's how this world is built. Too many relations of any kinds, to call it "simple".
