When they reach some defined age, their accrued benefits become available? I live in another economy and we have the concept of "preservation age" at which you can begin your retirement, this is somewhat more precise and distinct from "retire early" Surely their statutory benefits and personal payments cannot be withheld indefinitely? Frozen perhaps, and so declining in value absent contributions. A shitty move no matter what. I'm trying to understand if this is a misappropriation, a withholding of pension rights in the future.
