That's just a defeatist attitude then isn't it. I think it's better to proactively attack something even slightly evil, because if you don't it'll keep becoming more accepted until it becomes normal and starts rotting the very foundations of a civilized society.
It is very important to look at the "other side" of things, because there are people just like you and I on the "other side" in even greater numbers -- just not born in privileged homes with access to the same opportunities. On the other side of the Silicon Valley society that is full of white kids from high-income households with connections in high places you have poor black kids who're too poorly educated, who are more susceptible to getting had by mischievous advertising schemes of today. How this is different from pyramid schemes and other immoral -- but legal things -- is it's just more sophisticated... and I guess therefore, more effective, and therefore ultimately much more damaging.
(I have to add a meta-note, because this keeps happening over and over again: I think the last 4 or 5 times I responded to you I was upvoted and all of the follow-up comments you made to me were downvoted. I swear it's not me, I think it's a pity that this happens. As much and as often as I disagree with you I do like engaging with you because you're generally pretty thorough and pretty smart. I mean, at least you recognize that advertising is something not so "good" -- a lot of people here don't. Here's hoping my upvote to you helps).
