Jane Austen is known for her feel-good romantic novels. They are safe books to read if you want to see love, joy, and a happy ending. Of course, Austen was perfectly aware that happy endings are not guaranteed, and that people's lives are full of heartbreak and suffering. She could have written stories that reflected these truths, but she chose instead to write stories that bring people joy.
In a world full of uncertainty and hardship, Jane Austen's novels are still popular among modern readers. Clearly, she knew what she was doing.
