Typically it has been up to the parents to teach values, and it was even still present in earlier forms of the modern education system. Classical education is a good example of this in my opinion. I agree that technology amplifies both sides of the spectrum, but I can't help to think that it become a little harder to navigate what we might consider "good and evil" when we've mostly abandoned consistency in morals. I have a gripe with subjectivism when it comes to morals. I wouldn't say that technology and modern advancements is to blame at all, but mostly what we may have abandoned on the way. I'm not a pessimist about it though.
