“Unless we plan our resources purposefully, unless we are prepared to accept the disciplines that are necessary, we shall not be able to meet the challenge of the Communist world. As the years go by, and the people see us languishing behind, trying to prevent the evils of inflation by industrial stagnation, trying all the time to catch up with things because we have not acted soon enough—when they see the Communist world, planned, organised, publicly-owned and flaunting its achievements to the rest of the world—they will come to be educated by what they will experience. They will realise that Western democracy is falling behind in the race because it is not prepared to read intelligently the lessons of the twentieth century.”

2014, Address to European Youth (March 2014)
Context: In the end, the success of our ideals comes down to us -- including the example of our own lives, our own societies. We know that there will always be intolerance. But instead of fearing the immigrant, we can welcome him. We can insist on policies that benefit the many, not just the few; that an age of globalization and dizzying change opens the door of opportunity to the marginalized, and not just a privileged few. Instead of targeting our gay and lesbian brothers and sisters, we can use our laws to protect their rights. Instead of defining ourselves in opposition to others, we can affirm the aspirations that we hold in common. That’s what will make America strong. That’s what will make Europe strong. That’s what makes us who we are. And just as we meet our responsibilities as individuals, we must be prepared to meet them as nations. Because we live in a world in which our ideals are going to be challenged again and again by forces that would drag us back into conflict or corruption. We can’t count on others to rise to meet those tests.
