In the past, individuals could suffer death or disability due to small genetic defects, for example in their immune systems, for which modern medicine now routinely substitutes and which welfare cushions. But even modern medicine and welfare have their limits. W.D. Hamilton stated that when the misery resulting from mutations grows too great to bear — for medical, economic or humanitarian reasons — the load will be reduced, either naturally or artificially — painfully through elevated rates of mortality, or painlessly through eugenics.
