As we peer into society's future, we -- you and I, and our government -- must avoid the impulse to live only for today, plundering, for our own ease and convenience, the precious resources of tomorrow. We cannot mortgage the material assets of our grandchildren without risking the loss also of their political and spiritual heritage. We want democracy to survive for all generations to come, not to become the insolvent phantom of tomorrow.
__Dwight Eisenhower, 1961
I had to revisit this Republican President's words for some other reason, but the guy did manage the winning of WWII in Europe ... he has some "street creds."
I'd like to think that Reagan and our two Bushes had something to say, but this 1961 speech says it all.
Read this, too ... there are a few odd bits in each speech (delivered in historical context), but any commentator would be well-served to read both, in their entirety.
In contemplating the causes, which may disturb our Union, it occurs as matter of serious concern, that any ground should have been furnished for characterizing parties by Geographical discriminations, Northern and Southern, Atlantic and Western; whence designing men may endeavour to excite a belief, that there is a real difference of local interests and views. One of the expedients of party to acquire influence, within particular districts, is to misrepresent the opinions and aims of other districts.
George Washington, ~1796
