In many ways, there has never been a better time to be alive. Violence plagues some corners of the world, and too many still live under the grip of tyrannical regimes. And although all the world’s major faiths teach love, compassion and tolerance, unthinkable violence is being perpetrated in the name of religion.

And yet, fewer among us are poor, fewer are hungry, fewer children are dying, and more men and women can read than ever before. In many countries, recognition of women’s and minority rights is now the norm. There is still much work to do, of course, but there is hope and there is progress.

How strange, then, to see such anger and great discontent in some of the world’s richest nations. In the United States, Britain and across the European Continent, people are convulsed with political frustration and anxiety about the future. Refugees and migrants clamor for the chance to live in these safe, prosperous countries, but those who already live in those promised lands report great uneasiness about their own futures that seems to border on hopelessness.

Why?

A small hint comes from interesting research about how people thrive. In one shocking experiment, researchers found that senior citizens who didn’t feel useful to others were nearly three times as likely to die prematurely as those who did feel useful. This speaks to a broader human truth: We all need to be needed.
