You can also argue that instead of spending all that money to essentially sweep the problem under the rug, the state could be putting it to better use by giving it to medical and research facilities, who are working towards eradicating such disabilities.
With that point you can actually kind of gain the moral upper hand (if you do it rite, and if your opponent isn't too smart) because then you can claim that your proposal is a more permenant solution, and what the opponent is arguing is actually just a stop gap, a very expensive christmas card, that the state sends out each year hoping to avoid the problem until next christmas.
Use the christmas metaphor and bitchslap your opponent with his own morals.
