Before you can even have this conversation, you need to define what "work" is and take into account the stressors of that work, the abilities of the workers, etc. This mentality of "us vs them" when someone wants to ask "who works harder" accomplishes nothing aside from pointing out disgruntled laborers who got suckered into punishing jobs for laughable compensation.

It stems from this a twisted pride, typically from the laborer side of things, that I have seen so many times I've come to just expect it from them. The problem with that stance is that it falls apart with any scrutiny, after the laborer who wants to call someone else out for "not working as hard as they do" realizes that they are being exploited, which is nothing to be prideful about.

It's silly, as was your contribution to this conversation. I recommend reframing it as each position being important to the team, but requiring different demands and skill sets to which different people can contribute. It's not a competition and nobody wins by trying to diminish the contribution of others.

The only morally acceptable form of bigotry in society is against the lazy & stupid.

So if you want to hate, you need to turn everything into one of those two things.
