Pretty much. The only question is the level of detail. E.g., can I remember the exact date I started working at Maples Concrete Co. when I was 13 yrs old? Maybe, but if not I wouldn't be off by more than a month or two.
As to your question of 'cost' etc., I think a quick review of SS records or tax records might be enough to establish that the applicant is not an identity thief. E.g., it's easy for me to remember my summer jobs during high school 35 yrs ago, but a thief wouldn't know about those. Those jobs can be easily confirmed with access to SS records.
I notice the matter of delayed birth certificates seem to be of concern. I find that interesting. The questions most seem to object here are for those who were issued a delayed BC after 1 year of birth. I strongly suspect these are the types of question required for, and found on, a delayed (type #2) BC anyway.
I really don't see a better alternative for those who cannot provide adequate documentation (a normal BC).
