Many investors lost money over the past couple of years, but the endowments at prestigious universities suffered even worse. Investment performance at Harvard and Yale "badly trailed" the results at the average college, as The Wall Street Journal so delicately put it. I'm shocked -- but not because of these endowments' lackluster returns.

With exotic strategies and illiquid investments, Princeton registered a 24% loss in 2009, while Cornell took a 26% hit, and Harvard suffered a 27% drop. Compare those losses to the 18% drop for the median large endowment. Worse yet, many such institutions fund their operating expenses with the capital from endowments like these. If they don't generate capital gains, they may be forced to cut budgets and slash salaries.

So what?
Rather than relying on capital gains to sustain our own budgets, we need to seek additional safety in the power of ever-increasing dividend streams. With such a strategy, you'll never have to float debt in order to avoid whittling down your principal. Princeton only wishes it could say the same.

The companies below provide a dividend yield at least as high as that of the S&P 500 (about 2%), and they've grown their dividends at more than 5% per year over the last half-decade:

McDonald's has offered us a lot of dividend growth over the past five years, but its sustainable dividend growth rate suggests that it may have to slow that growth in the future. Still, its nice payouts have led me to call Mickey D's the dividend play of a lifetime.

Brookfield Properties has offered us dividend growth at an average of more than 10% a year for the past five years, and its sustainable dividend growth rate suggests that it may be able to continue that growth into the future. In contrast, National Retail Properties offers a high dividend and has seen even greater growth over the last five years, but its negative sustainable dividend growth rate suggests that its past growth may have been too fast to project into the future.
