Doesn't surprise me because social anxiety disorder is more likely to go untreated and bipolar people at least have highs and don't necessarily have anxiety, which is more debilitating in the modern world. Schizophrenia symptoms are bad though because they effect motivation etc negatively.

With its ceaseless boom and bust cycles, capitalism is itself fundamentally and irreducibly bi-polar, periodically lurching between hyped-up mania (the irrational exuberance of 'bubble thinking') and depressive come-down. (The term 'economic depression' is no accident, of course). To a degree unprecedented in any other social system, capitalism both feeds on and reproduces the moods of populations. Without delirium and confidence, capital could not function.
Also supposedly schizoid personality disorder actually has the lowest quality of life for mental health disorders, especially if you also have autism:
SPD is a poorly studied disorder, and there is little clinical data on SPD because it is rarely encountered in clinical settings. Studies have generally reported a prevalence of less than 1% (a few estimates, however, have been as high as 4%). It is more common in males than in females. SPD is linked to negative outcomes, including a significantly compromised quality of life, reduced overall functioning even after 15 years and one of the lowest levels of "life success" of all personality disorders (measured as "status, wealth and successful relationships"). Bullying is particularly common towards schizoid individuals. Suicide may be a running mental theme for schizoid individuals, though they are not likely to actually attempt one. Some symptoms of SPD (e.g. solitary lifestyle and emotional detachment), however, have been stated as general risk factors for serious suicidal behaviour.
Several studies have reported an overlap or comorbidity with the autism spectrum disorder Asperger syndrome.Asperger syndrome had traditionally been called "schizoid disorder of childhood", and Eugen Bleuler coined both the terms "autism" and "schizoid" to describe withdrawal to an internal fantasy, against which any influence from outside becomes an intolerable disturbance. In a 2012 study of a sample of 54 young adults with Asperger syndrome, it was found that 26% of them also met criteria for SPD, the highest comorbidity out of any personality disorder in the sample. Additionally, twice as many men with Asperger syndrome met criteria for SPD than women. While 41% of the whole sample were unemployed with no occupation, this rose to 62% for the Asperger's and SPD comorbid group. Tantam suggested that Asperger syndrome may confer an increased risk of developing SPD. A 2019 study found that 54% of a group of adolescent males aged with Asperger syndrome showed significant SPD traits (6% meeting full diagnostic criteria for SPD, compared to 0% the controls).
I imagine the deadness that accompanies schizoid PD and schizophrenia reduces some of the acute suffering though.
I think when societies reach a certain level of unhappiness usually linked in part to economics and perceived scarcity, they find a way to trigger a war, and then feel happier after the war.
