Imagine two worlds. In one world all people are completely and absolutely identical and unable to change themselves in any meaningful way. In the other world people are all completely identical, but able to radically reshape themselves as they see fit.

In one world an individuals actions and decisions would largely determine their outcome. In the other world things completely outside of an individual's control would be the primary determining factors in their outcome.

One of these worlds would imply the need for systems directly subsidizing those who fail to achieve. In the other world, poor outcomes would be attributable in large part to poor decisions. The latter scenario doesn't necessarily preclude a subsidization of those who fail to succeed, but it makes it a much more tenuous proposition.
