Independence of Koreans people

I had two Korean sessions in the this morning. Interestingly, both of them asked me why Koreans people get independent until so late. (I felt interested)*. I don't know why. It is a cultural thing. Many parents tend to support their child financially and emotionally. They care about them a lot. Surely, I cannot generalize it. It depends on the (situation)s* or the people. Someone get independent early as soon as they graduate from high school in Korea. (But)*, on average, many people usually get independent after they get a sustainable and stable job. If we become independent, we should make money to survive, and we should spend more money when we live alone than when we live with our parents. We should pay rent, groceries, and household goods, etc. Many parents in Korea think that if the student does not focus on his/her study (studies)* because they have to work to earn money, then (it wastes time)*. So, parents persuade them to live together, and save money, and do study more instead of making money. However, I don't think that way. I (leave out)* left my parent's home about 2 years ago. I can learn many things after I get independent. I should take responsibilities to work. For example, I always go to the working place on time, and I learn how to socialize with others. That kind of things might be more important than studying. We can be an adults eventually by solving our problems our own way. I haven't asked anything to from my mom, even though it makes me frustrated and annoyed.
We cannot judge other people's life lives. (Every lifestyle)* life styles is right. We have no right to judge whether other's another person's life is good or bad. How about you? Do you prefer living alone or living with your parents?

*You can just say: I found it interesting (for ideas/discussions/abstract concepts). Interested is used more for people and things, like interested in a car or the girl next door.

*Situation is almost always singular.

*You can use However if you want to say but in front of the sentence. However, but is also correct, but it is more colloquial.

*Studies is always plural.

*It is a waste of time is a more common expression.

*Leave out means to be excluded. Example: Your friends watched a movie without you, you got left out.

*You always have to use a singular noun after every.
