An earlier post asked "Are there more crazy people now?" and the body of the text focused on how the pressures of environmental "triggers" have increased for most causes.
The genetic portion which is responsible for 60%-to-85% of the cases was not discussed in that post.
Are more people carrying "crazy-genes" then they did in the past?
The short answer is "yes".

| Life was a constant struggle for sane, well adjusted people in the slums of Limerick, Liverpool and Hamburg. It was fatal for crazy-people. |
As recently as 1900 in developed countries like Ireland, England and Germany, if your mother was crazy you were probably not going to live to see your first birthday.

| Infant mortality in Ireland starting in 1930 at 85/1000 live births in urban areas. |

If you were a crazy-woman, your best chance of getting married was to get pregnant and "trap" an impulsive man. There was a pretty good chance he was also crazy or was an alcoholic.
As her child, your best hope for survival was to be placed in an orphanage, which in turn greatly reduced your chances of marrying and producing children.
In total, crazy-genes had a high probability of "dead-ending". In those days the pool of crazy people resulted from random meetings of recessive genes or in new mutations.
Flash-forward to the permissive, Welfare-State
Anecdotally, one of our local characters who was called "Homeless Girl" had five children before age 25 and they were all removed by Child Protective Services because:
- She was homeless
- She was addicted to drugs and could not care for them
Eventually, she O.D.ed in the bathroom of a fast-food restaurant.
The average woman in the United States has her first child at age 27-1/2 years.
That means that this crazy-woman had FIVE children before the average, not-crazy woman had her first. And all of the crazy-woman's children survived.
This is happening (with minor variations in the details) all over the United States and Europe.
Numerically, that means that back when "crazy-genes" self-extinguished we experienced a rate of approximately 5% seriously crazy people. Now the crazy-people genes are subsidized rather than exposed to Darwinian selection and the numbers are growing much faster (due to high risk behaviors) than the numbers of not-crazy people.
