I'd say this of low- or first-level managers, but not the middle layers.

Those are filled with people who are clinging to their roles well past their usefulness, because even though they're ruining social supports like Medicare and Social Security by pulling out multiples more funds than they ever contributed, they also failed to save anything of their own or are otherwise refusing to retire and leave the workforce (even though they've already started receiving "retirement" benefits).

FYI, people don't get to "pull out" funds from social security. You get paid what the government computes you'll get.

So which is it? They failed to save therefore they can't retire, or they could retire but are "refusing to"?
