I saw a point of view before, and I thought it was quite interesting. If you are an only child, you may not feel it when you are a child, because most of the classmates around you are only children. But when you grow up, you will find that the form of the only child is actually very unnatural in human society.
Look at your parents and grandparents, they all have many siblings, but you are the only one. Looking at foreign countries, many countries have siblings, and it is rare for an only child to be an only child.
In Japan, for example, anyone who has watched Japanese anime knows that it is common to have siblings in the family. The male protagonist usually has a younger sister or older sister, or has a younger brother with a large age gap. There are also often sibling or sibling relationships between classmates. It can be said that non-only child is the norm in human society, and only child is the abnormal state.
This state of affairs has also led to differences in people's attitudes towards epidemic prevention. Single-child families will definitely take epidemic prevention seriously, because there is only one child. In countries like Japan, where a family has several children, they may not pay much attention to epidemic prevention, because even if one child dies, it will not be broken. This concept is subconscious, not that everyone will think "I have several children, it doesn't matter if one dies", but because they have many children, they will not be too entangled in the issue of inheritance, and they will naturally be less vigilant in this regard.
In general, the generation of only children has lived a different life since childhood, and their upbringing and family environment are different from those before and abroad. According to a certain author, they are taught from an early age how to be a "captain", that is, how to cope independently with various problems in life. At home, they have to face everything alone, with no siblings to share responsibilities with. They have always played the role of captain, taking the helm and dealing with various problems.
When these only children enter the school, their relationship with their classmates can easily become like a separate "captain". Because everyone is an only child, they are Xi to dealing with problems independently, and rarely think of division of labor or helping each other. It's rare to think that you can be someone else's "first mate" to help someone else complete a task.
Of course, the school will also cultivate students' ability to divide labor and cooperate. However, learning to work together Xi is different from getting along with siblings from a young age, Xi being accustomed to division of labor and cooperation. The former is an acquired cooperation skill, while the latter is a life Xi attitude. Just as your Xi to reading and your ability to read are two different concepts.
The word "deprived" is really not quite accurate. The lifestyle of an only child is not deprived of anything, it just has its own unique characteristics and challenges. Just as we cannot assume that a person is deprived of his liberty just because he has learned self-discipline, we cannot assume that an only child is deprived of anything just because he needs to deal with life's problems independently.
Of course, the only child's lifestyle does lack some opportunities to develop collaborative skills. But that doesn't mean they lose this ability entirely, just that it may take more time and effort to develop.
In conclusion, the lifestyle of an only child is not deprived of anything, it just has its own unique characteristics and challenges. We can't simply blame all the "bad side" on "being deprived."
