Those who in that position still want a bigger house, more food, a yacht, expensive sports car and a harem; they're still in survival mode _after already having survived_ past any meaningful definition of survival. I don't know that I agree with you at all on this. I don't think a healthy person ("abundance mentality") can ever have too much of whatever it is they value. That's not to say that you're not happy with what you have or always unsatisfied. Only that you're always seeking to expand your "life," whatever that means to you. To make your life abundant. For many healthy people, that might include yachts, cars, more travel, more pursuit of hobbies, growing their business, improving their love life (for this, having a harem is probably not a great strategy), improving the world's political situation, expanding knowledge, etc. I think the viewpoint you're advocating really just reduces to giving up on values, i.e., asceticism.
