We might be all considered 'useless'* but the key is to put that 'uselessness' together and make something out of it.

Extended version (optional)

This is how even the lowest of "low-value" people I feel can come out from being scored as 0 (compared to a specialist) and still hit well as a score overall and even sometimes score better collectively than a specialist (sniper vs. above average soldiers or universal soldiers)

* "useless" here means the opinion of a pessimistic casual observer that someone (anyone) is seemingly unuseful because that person doesn't see that their distant perspective clearly restricts their view (especially if pre-disposition is to be a sceptic / doubtful / pessimist more than looking for positives and working with many good points)

Even liking people is a better start, knowing they are often impossible to be that bad (it's hard to to find a terribly un-able person once you talk to them!)
Looking from the outside and without deeper conversation obviously leads to people seeing people as less useful.

As always, just takes more time to find it.
And even some skill by leaders to use it which could be said for modern day rulers standardising / boxing people badly! (In that sense there is not enough boxes / choices for people to fit in!)
