    I hear you, but genetic change at the level of these diseases and traits can take on the order of hundreds of thousands of years or more to accumulate into meaningful trends. Social society is a part of that process, in the way it might be for other social animals. If social dynamics tend to result in communities harboring vulnerable individuals, then there is probably some selective advantage to that behavior, not the other way around.
