An evolutionist should not support government-cost-controlled healthcare.
Evolution teaches that species develop, adapt, and ultimately change based on individuals survivability based on small variations. Some variations make an individual more able to survive in its environment and others make it less able to survive. Individuals that survive longer will reproduce more, so favorable traits will be passed to the next generation than unfavorable traits.
If people have higher healthcare costs than they can afford, they are a drag on the species, must consume more than they can provide in order to survive. They have more unfavorable traits than favorable, and evolutionarily, should not survive. How much evolutionary harm is being done to the human species by maintaining the health of individuals who cannot do it on their own, and thus enabling those with unfavorable traits to pass them on?
Evolution values premature death as highly as longevity, or perhaps even more highly. Without early death, unfavorable traits would accumulate to the point where a species could no longer survive, and extinction would occur. Only those who can adapt to their current environment and survive in it should be allowed to pass genetic information to another generation.
