This reminds me of a discussion I once had with an anti-vaccination parent who asked if I would write "some sort of exemption" for her child's minimum school immunization requirement.
"No, I don't think I'll be doing that" was the answer, with a reminder that diptheria alone killed about 14,000 people yearly in the U.S. at it's peak during the 1920s, a great many of them children, with post-vaccine mortality now down to zero.
Our current standard of living ironically provides the environment for some to ignore or decry what it took for us to get us here in the first place (much of it during the time period in those pictures) and to fail at doing their part in maintaining that standard.
But alas, DB 2/2 is right; the stupid will select out, though apparently not before damaging their society in the process.
