SSN is voluntary. If parents would stop opting-in their babies into this data scheme, Americans could grow up without these numbers.
After ominous threats about 'must choose name for baby' my wife and I left the hospital with our baby. Health insurer sent new member card with name 'baby girl' which worked great for all the follow-ups. And nobody from big government forced me to apply for SSN. We did get a passport (SSN on that application is optional) and travelled internationally before the first birthday.
Most of this nonsense data collection is voluntary. More and more in life I say "No thank you" and move on. Many Americans get a warm blanket feeling by putting their children into voluntary data schemes.
