This country's prosperity has long been built on a great sucking sound: we've long attracted people with gumption, entrepreneurial spirit, and sheer willingness to work for a better future from all over the world. And that's great, because oftentimes those of us who've been here awhile need their energy.
Right now, old people (over 65) are about 12.5 percent of the population; in 2050 (when I don't expect to be around) elders will be 20 percent. It will be immigrant workers, a first generation in this country busting their butts to give their kids a chance, who are going to take care of all those old people. They'll be the folks paying taxes and FICA -- we need them.
You don't have to believe me about this. Listen to Fareed Zakaria, a journalist, editor at large at Time magazine, and a citizen-immigrant himself.
Zakaria is unafraid; he looks at the genius of his new country and sees successful generosity. What's the matter with so many of us, especially older people?
