More generally, someone who lacks status-regulating emotions won't have a fragile, hypersensitive ego, i.e. what most people (though by no means all) usually mean by "having a massive ego" or an "ego problem". Note that by this definition, many people whose self-esteem is founded in clear and verifiable achievements would be said to "lack status-regulating emotions". In many circumstances, it's not viewed as a negative trait.
