This is a great idea.
According to Belmont County Department of Job and Family Services Director Dwayne Pielech, his organization is looking into the possibility of paying women not to get pregnant. … Pielech said certain community groups may be able to offer a stipend to the women for each year they do not get pregnant. Each woman would have to meet certain requirements, and the program would be on an entirely voluntary basis.
If they can figure out a good way to make sure the women are honest, I say go for it!
