Who's creating any underclass? There's no reason to expect you won't just take a pill to change our eye color etc. It could be cheap and available. Not yet time to pull the emergency stop cord, because of imagined inequalities in a system that's not even been engineered yet.
Have you observed how the real world works? There are many diseases whose cures/preventions are "cheap and available" yet still continue to kill millions in the "underclasses."
GP made a fair point, and was not overly sarcastic.
EDIT: I appreciate the urge to have a kinder and gentler HN, but let's not start cluttering up threads more than we have to with references to the guidelines. It's meta, and meta kills.
Have you seen the unregulated medical systems in 3rd world countries? Easier access to antibiotics etc than in Malibu. Failure to cure diseases may be more about culture than price. Not warranted to jump straight to Gattica horror stories.
There are indeed many examples of this, especially in third-world countries ruled by dictators or superstitions, or a combination of the two. But that doesn't stop us from creating those cures/preventions for ourselves, because it's still the right thing to do.
We may eventually get through to them, at any rate. See Bill Gates and Polio vaccines, for example.
