요즘 어린이들이 과거보다 성숙하지 않다는 것에 동의하냐?
Children nowadays are more immature than in the past.

동의.

I agree that children nowadays are more immature than in the past.

First, they are stupid and out of control. We should teach them properly because they do not know what is right or wrong.

Second, Children nowadays are dependent on their parents because they have been raised under the over protection. They are insisting and crying when being dissatisfied.(unsatisfied가 맞나요 dissatisfied가 맞나요??)

For example, My son is 17 years old. but, he still acts like a kid. He does not know the importance of study. It is serious problem.

Therefore, Children nowadays are very immature.
