This actually did occur to me some time ago. I remember watching a program about the major tobacco companies, and some one was saying that cigarettes were very nearly the perfect product. The reasons went something like:
1) Fairly inexpensive to produce
2) Fairly inexpensive to the consumer
3) Not reusable
4) Very addictive
5) Fanatic brand loyalty
If it weren't for the fact that this product will shorten the lifespan ( and, therefore, the length of time the customer will continue to purchase the product ) of the customer, and the inherent risk of product liability suits, it would be perfect.
It came to me that there was, in fact, a better product. I give you Paradise:
1) Zero cost to produce
2) Consumer cost can be driven up based on the ability to pay
3) Consumer continues to pay for product his entire, unshortened life
4) Consumer cannot use it until he dies:
a) No one can complain that heaven isn't "as advertised"
b) No refunds to dissatisfied customers
c) No lawsuits brought by dissatisfied customers
There are a couple of things I would have done differently:
1) No stupid certificate. It unnecessarily drives up the cost, while producing no real reassurance.
2) Ironclad guarantee of Paradise despite behavior
3) Assurance that Paradise is as good or better than heaven
Ethically, I could not bring myself to market this product.
