Why do parents only have the obligation to raise their children to 18 years old, while children need to support the elderly until they are old?

Parents should raise their children to 18 years old, while children need to support the elderly until they are old. This is the law and human nature.

The reason why this provision is made at the legal level and in the field of social ethics is because of the following reasons:

1, the reason why parents want to raise their children is because they have no independent survival ability when they are minors.

For children who can't live independently, they can't live without their parents' support.

Therefore, from the social ethics and even the law, parents are required to raise their children.

2. The reason why the upper age limit for parents to raise their children is 18 years old is because at this age, the children will be adults. ...

As an adult, children have the ability to live independently without the support of their parents.

Adult children have no difference in social status from their parents. You don't have to be raised by your parents.

Therefore, the upper age limit for parents to raise children is 18 years old.

3, the reason why children support the elderly until they are old is because of the following two reasons:

First, parents have worked hard for their children all their lives, and children have the obligation to support the elderly.

Second, the elderly are getting older and their physical condition is getting worse. ..... Moreover, the older the elderly, the worse their physical condition. ..... This requires children to support the elderly until they are old.

It is for the above reasons that parents will raise their children to 18 years old. And children have to support the elderly until they are old.
