A bit pedantic, but that's not really the Kant thing. Kant is a proponent of deontology, which is utterly unconcerned with consequences. His thing was more checking if it would still make logical sense. That is, when he asks "What if everybody lied?", what he's getting at isn't that it'd suck if you couldn't even ask for the time and get the right answer, but that it'd destroy the concept of truth, and with that what does "lying" even mean? Kant answered the specific scenario of "What if the Gestapo wants to know if you're hiding any Jews?" (his actual scenario was with a murderer looking for a victim, since Nazis weren't a thing yet), and said that yup, you do not lie, because to him the morality of an action is unrelated to its likely consequences.
