> For some (not all) libertarians, "equal rights and opportunities" means that a healthy college grad and a schizophrenic homeless person have an equal right to apply for the same job, and if the latter can't get a job or any support and starves to death in the street, society's hands are clean--after all, they had the same opportunity as anyone.
The libertarian retort is that society's hands are not clean. Whether a homeless person starves without government assistance is a reflection of society. You are not obligated to let it happen just because men with guns don't force you not to, and it is a reflection on you whether you do or not.
And, so the libertarian argument goes, in order for the homeless to be fed with government assistance you need a majority of citizens to vote for programs to help the homeless. But if you have the support of a majority of citizens then they need only vote with their wallets and no government action is required.
More than that, when you put the burden of helping the poor on the government instead of individual members of society then when the government fails to do what is necessary each person need only shrug and claim "I paid my taxes" to be absolved of their inaction in the face of it.
