Ask any mobster.  The mafia business model is simple: Offer convenience and cures.

If you need a loan, you can get it from the mafia quickly.  It’s convenient.  Then, if you get over your head in debt, they’re there to help.  They’ll burn your restaurant down and collect the insurance.  That’s the cure.

Need something else?  They’re open all day.

So, how is the CVS business model any different?  If you need a snack, you can get it quickly.  It’s convenient.  Then, when you’re sick with diabetes, they’ll set you up with some insulin.  That’s the cure.

Need something else?  They’re open all day.

No, CVS won’t burn your house down.  But, they might kill your family.
