The observation is that the "take take take" behavior arises out of a sort of survival-of-the-fittest mechanism. Both preceding comments seem to lament this, rather than relate to it.
It's not about you. It's about another "type" of human. One that wants more. Maybe you don't (good for you, probably you are happier!). But the problem is you will need to "fight" against the other "type". What do you (personally) do then to prevent the other "type" grabbing more? Whatever other people like you tried during history (hundreds of years ago) seems not to have worked (the grabbing types are still grabbing in all culture I have sufficient knowledge of to comment on).
