Just because these people can’t vote yet doesn’t mean they shouldn’t have rights or be treated with dignity and respect like the rest of society.
The problem is mostly not the people, but the social media services, that take advantage of them for as much profits as inhumanly possible, and in the process affect their personality in a wrong way.
Sometimes I too feel that they shouldn’t have a smartphone, but in reality it’s a problem with these corps and their motives, who affect everyone else too but has deeper effects for young people.
But the solution also involves parents raising their kids, instead of youtube, facebook, tiktok and whatever else. To some extent it also means having some oversight on what their kids see online.
