They make their products addicting, because they want you to keep using it, so they will keep on existing in the future. I doubt they care about the population at large, since that is something no one organization has control over.
My suggestion would be to look at this from a bit smaller scale and not care as much at the world at large. First, because you have little influence on the latter and secondly, I think that caring about the community around you is a much more meaningful way to live.
Of course I might be wrong and everybody has a different view on what brings meaning to their life. I just say this, because I used to think more like you and noticed it always brought me in a negative, unconstructive spiral.
