Not only that - having kids effectively gives the state massive leverage over you to enforce whatever they want. If you have kids and no job, good luck to you. Mr Goverment says, "So, naturally, you need to take this injection, right? Otherwise you lose your job and your kids starve. Oh, glad you are 'willingly' taking it. It's not like you can fight me, after all, your kids might get harmed and it'll be all your fault!"

No kids and no job? Whatever, no need to sacrifice my principles for you.
