on one hand, yes: people with strong Cluster B personality disorder tendencies (well, narcissistic and anti-social at least) tend to float to the top in capitalist societies. On the other hand no, because these diagnoses are harmful for us poors, and can be used to deny necessary care. Borderline personality disorder is an especially common misdiagnosis for autistic women, and the drugs they pump all of us bpds with do more harm than good and therapists specializing in dialectical behavior therapy are few and far between. In my case I got overmedicated and undertherapized, and eventually just dumped and told to get a job. (/rant).
