There is a very good article addressing this by David Mamet at the Daily Beast. Essentially, he says that defining "need" is not any business of the government, and that any attempt to do so leads to repression and violation of rights.
Carried to its logical extreme, legislation of "needs" leads to "From each according to his ability, to each according to his needs." We don't want to go there.
If you find yourself in a fair fight, you have not prepared properly.
