скажите какие жизненно главные и главные задачи дети решают в 21

I always thought, that children and teens could not have any problems. Parents take care of them, feed and buy clothes or something else, give education and development. But its not all for young generation. Children and teenagers are very picky now. They want modern expensive phones, computers, pocket money. They dont want to help their parents. Not all, of course, but most of them. But lets go back for 10-15 years ago. Not every adult could have mobile phone or computer at home. Time is changeable, I know. But our parents do their best only for great future of their children. Nevermind, teens find different problems for themselves and their parents. They can quarrel, fight, envy or even steal at school. Its awful! I think, the modern mass media and internet make bad influence at them. And I guess, such problems will exist always. It mostly depends on parents upbringing and education. But at the same time children and teens should understand the importance of these problems and try to help their parents as much as they can.
