"centralization"
The idea that government reluctantly stepped in because communities and private solutions faded out doesn't stand up either. Go look up the numbers on private and religious support for the poor and needy.
Again, as with so many other issues, it's not that the private solutions didn't work, it's that there's no power to be had from them.
No politician ever got elected by touting the good work the Red Cross or Salvation Army does.
