For every, every single decision we take there is an affected part and a favored part.

There is no "it's good for all" decisions; in that cases we don't take into consideration the affected part. Because it's against our interests or it's not of our concern.

EG globalization seems to be such a good thing for us and global market; yet nobody thinks on the Third World. Mostly, because they have no voice on developed countries. But heck, let's enjoy it till it lasts.

We should stop when the affected part is greater than the obtained benefits. Even if it's against our interests; because we're not the only living thing on this planet. We're responsible of it, and what we make of it.
