Of course, now we have universal health care and an 'elf and safety culture, all manner of deleterious mutations can be accumulating in the human genome that would normally be eliminated through natural selection pressures.
Universal health care is not there to preserve the lives of the unworthy, but rather the lives of the poor - unless, of course, you particularly think those two are synonyms?
Similarly, health and safety in the workplace is primarily to prevent unscrupulous employers putting their workforce at risk - it's about protecting the poor, not the 'evolutionarily undesirable'.
