I often find that people confuse inner peace with some sense of insensibility whenever something goes wrong. In such cases inner peace is a permit for destruction: The unyielding optimist will pretend that the forest is not burning either because he is too lazy or too afraid to go and put the fire out.
The challenge of abating one with a genuine ego problem is to not try to put him down. Any and all antagonization, in his mind, is merely compensated for by his own descriptions: his feelings of persecution by the envious and his ideals of worth. Arguably, the genuine ego is more of a circumstantial defense mechanism rather than a steady arrogance in need of starvation.
It might be depressing, but it's also the truth that no one has the power, the money, or the resources to save everyone on the planet from going hungry, living in poverty or allowed basic human rights. But consider the other side of this: there are people in this world who truly WOULD do all of these things for everyone if only they could. There is hope after all.
