“Joyless children do not make good men.”
One of the causes Jacob Riis championed was building playgrounds for New York’s children:
I wanted the sunlight in there, but so that it might shine on the children at play. That is a child’s right, and it is not to be cheated of it. And when it is cheated of it, it is not the child but the community that is robbed of that beside which all its wealth is but tinsel and trash. For men, not money, make a country great, and joyless children do not make good men.
