A bull elk is a large animal, a tick is a small animal. The elk does not even notice when a tick fastens on and drinks his blood. When, however, untold thousands of ticks fasten on and drink his blood, he is weakened and becomes a target for a wolf pack. Likewise, a society may be wealthy enough to sustain itself if a small number of individuals who otherwise cannot contribute instead are given what they need to sustain themselves. But, should that number of takers become large enough, society will become weakened and eventually collapse. Far better for society to expect the able bodied to work and take care of only those who cannot take care of themselves and have no one to help.
