Why create new life when there is already plenty of kids existing who needs care and love?

If we are talking about adoption then no there is really a huge shortage of young kids to adopt in just about every first world country. The vast majority of adoptions are between family members. The vast masses of parent less kids and orphanages that used to exist have disappeared with widespread use of birth control and abortion. There really aren't that many kids being born in the first world anymore that are unwanted. This forces many who want to adopt to turn to international adoption which is incredibly expensive and also has constant scandals with some source countries turning it into an unethical industry with malevolent actors seizing kids from parents for made up reasons. Scandal after scandal has made more source countries outlaw international adoption which is furthering the undersupply. Many prospective parents spend years and years trying to find kids to adopt.

Now if we are talking about older kids that have been forcefully seized from their parents there are lots available even domestically. But these come with a lot of problems as they are often from broken households and sometimes have a history of crime and drug use. Very commendable to adopt one of those kids but it's a whole other beast than raising a child from a young age. In some countries such as my own you dont even become a legal parent when you adopt seized kids like this. They are officially under the care of the state and you are just a contracted caretaker. Can't even call yourself a dad or mom.
