the extended family is not common anymore
In our modern world, more and more adults are choosing to have their own family instead of becoming a part of a joint family, which is happening not just in America and Europe but also in the other continents. In my personal view, I do believe this is a good sign of our society despite many others' skepticism about this phenomenon.
There are definitely some tempting facets of contributing yourself to an extended family, especially in many traditional Asian countries. Fencing for yourself is never easy, which usually leads young people to the decision of sharing their lives with their other relatives. Also, living under one roof and spending quality time together is the best way to bond emotionally and physically with each other. This can be easily seen in many close-knit families.
Nevertheless, having your own family can open the yuppies to a significantly independent lifestyle. Paying small expenses is the very first step in becoming better versions of themselves. For that, people become more aware of the true value of their income. Working with other people to solve every problem you encounter also helps to improve interpersonal skills. Nobody can live without society, however, learning to handle the problem by yourself and seeking help from others always give them more initiation, reactiveness, and a sense of responsibility in their lives.
Plus, the number of conflicts over generational beliefs can reduce considerably due to the similarity between those born during the same period of time. Sometimes, commotions can arise over either minor changes or great upheavals in ordinary lives because of the difference in intergenerational opinions. Parents, let alone grand and great grandparents, are always notorious for their obsolete perceptions, viewed from younger generations, about many mundane issues such as equality or spending habits.
Overall, while living in an extended family seems to be a good idea, but it does not really fit in the mainstream mindset of many people anymore. There are many shortcomings and difficulties, however, it is irrefutable that a nuclear family can function just as well as an extended one and even better than in a number of aspects.
