I am surprised there is not more feedback on this episode.  Lego is correct it has much to say even more today as we socialism on the rise in our culture at it promises happiness for all.  This was written in the '70's but is even more applicable and potent today. 
The unmasking of sexual freedom as a lie and the allusion to the pain mothers experience long after the abortion speaks powerfully to us as well.  Rare in a program to speak philosophically but not be to preachy or corny.  This one really walked that line and nailed it.  I give it 8 out of 10.
