The truly "less fortunate" are those who are less fortunate in terms of brains. Studies show that they have a lower IQ level than those who are more mobile. This does not suggest some grand inequity in the system, however it merely suggests that nature does not create all men equal in their abilities.
The question is how society can rectify those imbalances, or if we actually should. The answer is clearly yes in some cases; everyone agrees that the mentally and physically disabled deserve societal protections. But if we get rid of the incentive for the non-disabled to work hard by giving them excuses not to do so, like attempting to provide equal outcomes for the non-equally gifted, we destroy the capacity for true class mobility. The beauty of a free society is that someone slightly less gifted who works harder than usual can rise; the burden of a free society is that someone slightly less gifted is expected to work harder than usual. The socialist society, however, is problematic on all fronts. With no incentive to work hard, those of all gift levels simply stop working.
When it comes to the "less fortunate," then, we must be careful about whom we are speaking. If we mean the poor, we must distinguish between the poor who are truly less fortunate, and those who are not. If we do not unpack the term, we run the risk of forwarding the socialist agenda without even knowing it.
