No, it doesn’t, because the left promotes “the ultimate birth control” of abortion.
Nothing the left does would EVER have the intention of reducing non-marital sex.
Everything connected to the left can be attributed to Thomas Malthus’ thesis, this being a world of limited resources and man’s rate of population growth will outstrip those resources.
The left supports abortion because it supposedly helps prevent population growth. The reason why the elites fear population growth is that they fear the lack of resources for themselves. It is why they feel the need to control everything.
