Why would people have kids when their kids are going to be so stressed out when they get older?

The first 18 years of a person's life are great. Sure, there may be times of stress if they get a lot of homework or hard school projects and they may get bullied sometimes, but it's mostly very good because life is very easy. Their only responsibilities are to go to school, do homework, do whatever chores their parents want them to do, eat, and sleep. After highschool graduation, life turns to absolute crap. -If you go to college, you have to study extremely hard and do a ton of homework, which is super stressful. If you get your college degree, you will have to search hard to find a job. You might not even find a job in your field, even with a STEM degree. -If you don't go to college, you will still have to search long and hard to get a decently priced job that allows you to pay your necessary expenses. -When you move out, you are on your own. You have to pay your own bills and rent, pay for your own food, entertainment, healthcare, furniture, vehicles, clothes, and everything else, make your meal plans and grocery lists, do all of the household chores, run all of your errands, and figure out how to do everything you didn't learn when you were a kid! To pay your expenses, you have to work 40+ hours a week at a job you might hate.You may end up struggling to afford to live on your own, even with a decently paying job. So why do people choose to bring kids into this stressful world? You have 18 years of fun, and then live the rest of your life in stress and misery.
