When it comes to the slowing economy, Ellen Spero isn’’ t biting her nails just yet. But the 47- year-old manicurist isn’’ t cutting, filing or polishing as many nails as she’’ d like to, either. Most of her clients spend ＄12 to ＄50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening economy. "I’’ m a good economic indicator," she says. "I provide a service that people can do without when they’’ re concerned about saving some dollars." So Spero is downscaling, shopping at middle-brow Dillard’’ s department store near her suburban Cleveland home, instead of Neiman Marcus.

Even before Alan Greenspan’’ s admission that America’’ s red-hot economy is cooling, lots of working folks had already seen signs of the slowdown themselves.

And most folks still feel pretty comfortable about their ability to find and keep a job. Many folks see silver linings to this slowdown. Potential home buyers would cheer for lower interest rates. Employers wouldn’’ t mind a little fewer bubbles in the job market. Many consumers seem to have been influenced by stock-market swings, which investors now view as a necessary ingredient to a sustained boom. Diners might see an upside, too.
