There was a sort of study conducted in, I think, Yugoslavia back in the 80's or 90's. Basically, when the authoritarian regime outlawed abortion thousands of unwanted children were born into poor and broken homes, because low income households are always much less likely to spend money on contraceptives, and then later when the democratic regime took over and unbanned abortions scientists noticed that there was a direct correlation with crime rates skyrocketing about 13 years after abortions were outlawed and dropping again a few years after the unban. I read this years ago and can't really remember the exact details, but I always thought it was really interesting to see, because it's really easy to say that all life is sacred, but you can't force parents to love and nurture those unwanted children. So the kids grow up to be delinquents and start ruining society. In a utopia abortions wouldn't exist, because every child would be planned and loved. This is not a utopia.
