My postulate: while the slippery slope won't necessarily find itself at the prescribed (induced) endpoint, there is a virtually unlimited timeline for the slippery slope to find itself to that endpoint. With that virtually unlimited running space, if continued attempts are made, eventually probability will necessarily yield a result.

I think this applies more to wider generalizations as opposed to very specific instances due to the nature of probability and finity of resources invested in continued attempts, but it can be applied in either scenario. Think Murphy's Law.
