It's also true that babies that sleep with their parents hasn't been a cultural thing in the US. I'd say that in the last 20 years, the number of people doing it has increased, which likely accounts for the increase in the numbers of deaths due to it.
Using this same logic, we should have abandoned the adoption of the automobile because as it became more and more commonplace, automobile-related deaths rose as well.
It's a simple trade-off or risk management. In the case of cars we accept the risk in exchange for our lifestyle (going to work, go to buy food etc) so this is an acceptable trade-off for most people (I like to reduce the driving risk by grouping errands, walking when I can etc).
In the case of sleeping with a baby you are taking a risk but for what reward? "cultural thing"? not having to sit up in bed and reach to the crib? this risk/reward ratio is horrible and cannot be compared with the one for cars.
* You can just as easily say that having your baby sleep in a crib runs the risk of you having purchased a 'defective' crib that will kill your baby and spawn a recall.
* You can easily say that putting your baby in another room runs the risk of something happening to your baby in the other room that you either can't hear, or can't get there fast enough to do anything about.
* Your baby can just as easily die from SIDS in a crib as they can in your bed, and SIDS is probably a larger risk than you rolling over on your baby (as long as your don't go to bed after drugs and/or alcohol).

Please tell me what the risk/reward ratio is.

Most people don't do risk/reward ratios. What is the risk/reward ratio of the majority of the populous zooming around in personal automobiles as opposed to pooling resources for effective (and well-maintained) public transit? In many of the places where public transit languished while automobile usage took off it had far more to do with the prestige of owning a car. Using public transit meant you were poor, but having a car (or multiple cars!) was a status symbol. Why do you think that you can find extremely 'pimped out' cars in the drive-ways of houses that are falling apart in places like Detroit? Why do I get teenagers/20-somethings (infrequently) yelling things like, "I got wheels baby! WHoooo!" (or similar) when I'm walking along a busy street? The car is a status symbol a hell of a lot more than it is a utility device (do you really need to drive 5 blocks to the store to pick up beer and drive back home?)
