Of course you're right.  Not too many would deny that.  It's just that we
don't want to change.  Well, we want to, but we've got too much invested in
our own crazy system.  Look at it this way.  I believe the being a
vegatarian is much healthier and in keeping with good karma.  But I ain't
capable of switching off my burgers and dogs, etc now.  

We might try to make the next generations more flexible and open to it
(especially for scientific pursuits) but that's our best hope.
