Context: in a flashback, a Cuban boxer is thinking back to when he was in Cuba before seeking asylum (亡命) and migrating to America. He had just won a gold medal for his country in the Olympics.
国のためとか… 小せェもんに縛られてるから底辺止まりなんだよ 凡人共が
My literal translation attempt is:
For their country, ordinary people remain in the lower classes because they are bound by little things.
What is the meaning of 小せェもんに縛られてる? I understand the literal meaning, but what is he actually referring to? Is this some kind of metaphor I am not getting?
Thank you for your help!
