There is more respect to be won in the opinion of this world by a resolute and courageous liquidation of unsound positions than by the most stubborn pursuit of extravagant or unpromising objectives.
George F. KennanActually, the inability of any society to resist immigration, the inability to find other solutions to the problem of employment at the lower, more physical, and menial levels of the economic process, is a serious weakness, and possibly even a fatal one, in any national society. The fully healthy society would find ways to meet those needs out of its own resources.
George F. Kennan...there is an optimal balance, depending on the manner of man's life, between the density of human population and the tolerances of nature. This balance, in the case of the United States would seem to me to have been surpassed when the American population reached, at a very maximum, two hundred million people, and perhaps a good deal less.
