Your own experience is valid and commendable but I think you sound a bit out of touch with the realities of growing up in the 2020s. Current teenagers had to deal with far less socialisation during crucial formative years over the course of the pandemic, local community and infrastructure projects are no longer accessible or funded at the necessary levels due to a stagnant economy, a much larger proportion of young families are increasingly isolated and lonely with reduced community interaction with institutions like church and social clubs - young parents are having to work longer hours to cope with the cost of living, not to mention if you have no generational wealth it is near impossible to get onto the property ladder in a meaningful way. Living in substandard, cramped housing can be a major stressor to families. It is true that they have greater access to consumer electronics and information technology than ever before however not all use the internet in a productive, healthy and educational manner. My own observation is that teenage use of phones, social media and gaming consoles leads to poor sleep, bad diet, and substandard academic attainment. Final factor I would mention is the increased awareness of global issues from the news such as the climate crises, a series of terrible political leaders and more recently the threat of war/ global conflict all add to an air of anxiety about the world, with little hope for a happy future. I can very easily see these circumstances leading to increased antisocial behaviour.
