Easy access to violent weapons, difficult access to mental health facilities, low education standards, poor future prospects, high support of celebrity and lobby groups supporting all of these things.

The difficulty with access to mental health facilities 100 is a big one imo.

Where do you house people who need longer term monitoring once they are cleared from the hospital?

They closed most state/fed funded facilities in the 60’s and 70’s. 

Most families aren’t equipped to deal with persons who need more intensive care/monitoring. 

Most households have two parents working out of necessity. 

Who helps to ensure mentally sick people aren’t out there hurting others? Whose responsibility is this when the person themselves isn’t thinking clearly and has severely impaired judgement?
