Duh. Value is holistic. We can find anything we want to find to support an argument.
When you have worked with someone that screams at their coworkers, can barely feed/clothe themselves or refuses to lift a finger to help you... then you will know how much time and emotional effort these behavioral traits can waste.
Toxic employees exist at the extremes of those buckets. Avoid hiring toxic employees, but the filters available to you might not be good enough to screen them out, so fire them quickly. During the interview, you might just be able to observe minor quirks which are hardly indicators either way.
I cringe whenever I read job ads that are aiming for a culture fit: "we only want to hire harmonious, independent, extroverted employees;" when in my experience, the best employees do not hold strongly to those ideals, but neither to do they hangout at the other extremes.
All or nothing hiring is too risky. Gradual formality makes the selection from both sides cooler, you know. We don't do interviews either; hazing sure, but no stupid hypothetical questions to test loyalty. There is no loyalty. Greed is good. =)
There is the another option. Make something people want and build it up slowly, on the side. If you do, you may free yourself from being at the beckon call of other masters (other than users). Others have, so it's possible. We are each masters of our own fate.
