Do you propose just letting the "children of those incapable" of working die?
"Chastity belts for unmarried women?" Now you are thinking!!! That would cure a lot of social ills, from children out of wedlock to STD's. But I'm afraid you are too late. Women can now vote. That cat is out of the bag.
Those incapable of working,should be provided for their families and charities, or by a compassionate STATE legislature. If a state govt will not provide for the care of the indigent, they will of course starve or very nearly. Elected officials will see to it that there are provisions for the truly needy.
The problem with the cost of caring for those injured in an accident(in the case of no seat belts), or taking care of those children with parents incapable of taking care of their responsibility, is one of too much socialism, not to few laws.
It is not my responsibility to provide for children other than mine, so I can mourn the passing of those few peoples that would. I would feel sad of course, but not guilty. They can adopt their children out, put them to work(if we could change the counterproductive child labor laws), or or be so selfish(read responsible)for the deaths of their charges.
IN truth, few are in that position, and charity would take care of their needs. People that are too proud to beg, are likely not to feel guilty about begging from the govt. As a matter of fact, they see the provision of their own needs, as a governmental right.
