wonder how people survived without vaccines in the past?
To be fair in an analysis of this issue (and many like it) it is important to mull over this question.
The answer is that a lot of times they didn't. They died of lots of things. I suspect that increasing human populations and urbanization which came with agriculture and such were a boon for certain pathogens. As a first-worlder, I can say that all the way up to my great-grandfather's time 'the weak ones died' to quote him (in what I'm sure was a thick Scandinavian accent although I never knew the man.)
One must understand the mindset of the modern Eugenisist. They tend to be wealthy and well educated people who are very aware of history. They will argue that the modern world needs a balancing force to offset the 'negative' effects of technology. They will feel that in using their wealth and power to provide this offset is a good thing and will be aware of their peers work on 'diet, injection, and injunction...' and many works of such a nature.
The above said, many of the eugenicists are not above making a dime off of their 'good deeds', so one would not be surprised to see a good deal of coordination between the 'philanthropists' and the corporatists (when there is a difference at all) and to see their policies and operations mesh quite nicely and result in a lucrative end goal. That is, more money and more power for themselves.
A very common mis-understanding of modern day eugenics is that it is geared toward making human kind 'better'. To Joe Sixpack 'better' means stronger, smarter, etc. This is not what it means to the average 2017 Eugenicist. It probably means exactly the opposite. Stronger and smarter people are a threat. Stunted and stupid people are not. I'm not surprised in the least that 'the autism epidemic' continues to grow and somehow the 'research community' cannot seem to figure it out...but they know for sure that it has nothing to do with vaccination.
