As long as the general public contains a certain % of assholes, there will be someone who needs to deal with them and tired of their shit. Not necessarily an IT support person. Perhaps a nurse, a hotel receptionist, a security guard etc.

Maybe there is a financial limit of compensation after which dealing with them stops being a problem - I would certainly personally tolerate an onslaught of assholes for a million dollar salary, at least for a few years - but that limit of compensation may be unrealistic to reach.

I am not sure how an utopia where people stop being assholes to one another could be achieved.
