I thought Teddy died in 1919? Anyways, whenever he said it, the world was much less complicated - his words are not unchanging like Holy Scripture (sorry to point out the obvious, but someone brought up the Bible above). I do not think illegal immigration is ducky - I am in favor of legalization.
Would you say that the same could apply to the Constitution? For example, some claim that the founding fathers could not possibly have imagined some of the advanced military-grade arms made today, and therefore, the average citizen should not posses them. Do you agree with this?
