It's certainly a complicated subject, but I'd just challenge you to think of the positive version as well, not just the negative (addiction/vices/&c). It seems you have a default negative view of the world, some of us have a default positive view of the world. Modern life is pretty awesome!
There might be something deeply wrong with the modern world (which by the way includes other countries ranging from, idk, Iran, to Vietnam, to Korea) but there are a lot of things deeply right about it: opportunity, human rights, women's rights, independence, opportunities to build rocket ships or sail the world. That seems like one hell of a gift that I wouldn't want to deny anyone. If anything, providing opportunities and giving human minds the chance to flourish and be creative seems less of a sickness and more of a cure.
Now imagine someone psychologically very average whose source of meaning is in the familiar environment where they have an acceptable amount of status, broad community support and much social engagement. They have a peculiar culture and social practices which gives them deep personal meaning. Now imagine all of that is swept away; no social status, no familiar environment, cultural practices gone, extended family scattered to the wind. What value does the wonders of the modern world have to someone who has lost everything they value?
Consumerism, technological marvels, and endless entertainment are the modern world's answers to the waning sources of personal meaning in modern life. Turns out that it's all a very poor replacement.
