In this ABO AU, Betas are the rarest designation, making up only a tenth of the world's population. Betas are considered second class citizens and are encouraged not to marry and have children. They almost always work in caregiving roles, traditionally 7 days a week, and are paid very little. Most of the world's major religions endorse discrimination in one form or another (maybe saying Betas were criminals in a past life, or Betas were only created to serve Alphas and Omegas).
Booker broke norms by marrying and having 3 sons, as well as engaging in forgery as a profession, rather than being a good little Beta. This contributed to his sons resentment as they were bullied by neighbors/other kids constantly.
Starting around the early 20th century, attitudes began to change, but being as old as he is Booker cannot shake his feelings of worthlessness as the only Beta member of the old guard.
The story could be about his relationship with the other team members (and the outside world) over time, or after his reunion with the team.
