Hypothetically? It's common for an industry to want to expand their market.

Imagine you're a big drug company, and you make decent profits selling drugs to treat shell-shocked soldiers returning from the front lines after losing limbs and seeing their buddies die right in front of them.

You look for ways to increase your sales and add to your profits. What if you could also sell your drugs to people who've been in bad car accidents? And to rape survivors? And to refugees fleeing from war? And to mothers who had particularly difficult births? And teens subject to severe bullying? What about cancer survivors, or people who've struggled following the death of a grandparent?

It's easy to see how higher diagnosis rates could go hand in hand with higher sales and higher profits.

I can see some logic in you're hypothetical but there are numerous other causal factors which seem much more likely.

Maybe, but I wouldn't dismiss hypochondria or mild hysteria that quickly. If you keep hearing people talk about skin infections, you'll notice yourself itching more...
