Children use to be born with a high chance of killing their moms during birth. Then half of them wouldn't make it to 18. Then could probably expect to live and work as a farmer under the control of someone else at the threat of violence for their whole life. Famine, disease, and many other unimaginable problems plagued their lives. Things are literally the best they've ever been. They could get much worse but any reasonable prediction still puts us ahead of the expected life of someone in the 19th century. If you don't want to have children, that's your choice. You don't have to justify it by putting your morality on other people.
