"when their kids no longer need any parental care."
At which age kids no longer need parental care? Being able to find the house is just a basic capacity. I see lot of jerks around exactly because their parents believe they were grown up enough to take care of themselves. Even more so in a society that pampers them in the wrong way, including school.
I'd suggest people who are not interested to grow children properly should avoid to have them in the first place. Creating a good adult is a very difficult task, and takes a lot of proper parental care. Having children just to show your reproductive organs work and have been used it's not a good idea.
