No, love is not "everything". It's only one aspect to life.
Anyone who "lives for the acceptance of others" will die from their rejection. Self-love/self-esteem are the key to happiness.
As one old very popular song once stated:
"The greatest love of all is learning to love yourself."
As for money, power, and prestige they have nothing to do with whether one feels loved or not. It's human nature to have an ego and have desires! Some people are more ambitious than others when it comes to pursuing their dreams and goals.
Too often people act as if you have to decide between being "rich and without love" or being "poor and loved". The truth of the matter is you can be (rich and loved or poor and unloved). One has nothing to do with the other!
