Talk about penny wise dollar foolish, pro-abortion math is the very height of this thinking. Let's pretend to forget for a minute that you are reducing the value of human life to estimated medicare savings.
Consider this, your thinking COSTS our nation dearly in terms of a loosing demographics battle. I offer my adopted home city as an example, Detroit. Like your thinking, Detroit sought to increase entitlements and government benefits. Likewise due to error Detroit committed a war of attrition against its own demographics all. You do it with abortion, Detroit did it with open hostility towards business and theft.
The end result? For every two people receiving city entitlements there are two actually paying into the system. This penny wise dollar foolish abortion scheming of yours results in the same end.
