Although I am not a medical professional, I am a literalist and I found the idea that hoarding is caused by trying to make a living in stressful times an interesting premise. Since I don't claim to be a medical professional, and I don't know why people hoard, I decided to look it up.

"The primary reasons for Hoarding are Biologically based rather than psychological...."

Frost & Hartl's ('96) definition of clinical hoarding.

This information about hoarding was also interesting reading:

• Hoarding & Saving Symptoms are found in 18% to 42% of OCD patients. But most people who Hoard will also exhibit OCD symptoms.
• 
  Less than 1% of the population Hoards (Non clinical populations are also known to Hoard.).
• There are other mental disorders in which Hoarding Behavior is seen, such as.: Anorexia Nervosa, Dementia and sometimes Psychotic Disorders.
  The differences between these types are not know yet.
• 4 keywords that are found when talking about Hoarding are.: Indecisiveness, Perfectionism, Procrastination, Avoidance.
• This is a symptom that is known to be difficult to treat, especially if there is little willingness to change.
• The usual medications that can help with/for many other OCD- symptoms seem to be less effective for treating hoarding. Same goes for the ERP that is traditionally used to treat OCD when it comes to therapies. But an adapted form of ERP is being developed of which the results will still have to be looked in to more thoroughly.
• BT ( Behavior Therapy.) does prove to show some benefits. But like mentioned above, do Hoarders not benefit greatly from the traditional treatments for OCD.
