When we spoke about workplaces in 1972 we mainly were referring to old-line manufacturing firms, on the one hand, and Main St. shops and restaurants, on the other. Both of those categories are now insignificant in terms of employment. Today, the economy is dominated by the rapidly growing Low-Cost Operators - national discount and mall chain stores, fast food franchises and supermarkets - which offer employees low salaries, few benefits and little training.

By all indications, American business leaders are more adept at creating business strategies than they are skilled at human capital management. American entrepreneurs are world-beaters when it comes to creating new businesses, and corporate managers are adept at using the latest marketing, financial, and technological practices.

If America is to compete effectively in world markets, its corporate leaders must strategically position their companies in the right businesses, and then manage their workforces in the right ways. However, the nation has a shortage of business leaders who understand the importance of utilizing human capital to gain competitive advantage, let alone the know-how to do so. In the future, that shortcoming promises to be exacerbated because few business schools today teach aspiring executives how to create the kind of high-involvement organizations.

Motorcycle manufacturer Harley-Davidson is a prime example of an American company that uses employment conditions to boost productivity. Current CEO James Ziemer - who started with the company while in high school has negotiated imaginative contracts with the unions representing Harley's workers, agreeing to keep production in the U.S. in exchange for constantly reducing total labor costs through automating tasks and changing work rules. Because Harley regularly reassigns workers whose tasks have been automated to other parts of the company.

In a nutshell, the ability of American companies to compete in world markets depends on creating conditions in which workers can add sufficient value to justify their higher wages and benefits, much the Japanese auto manufacturers have done in this country. Until unions and mangers understand the necessity of effectively employing the nation's most important resource, the American worker, we are destined to have more Detroits.

Managers who assume that higher profits drive better working conditions may have their logic backwards. Contrary to conventional wisdom, our research identified companies in virtually every industry that are profitable because they provide good jobs.

Recently, there has been a profound change in how we think about corporate leadership. The 1990s was the era of celebrity leaders: we focused on Jack Welch, and not GE, on Bill Gates, and not Microsoft, on Steve Jobs, and not Apple, on Larry Ellison and not Oracle. But, on reflection, the records of most high-profile leaders have not withstood closer scrutiny. In almost all cases, it turns out that the success of organizations is due to the collective efforts of many, and not to the genius of a single, all-powerful individual at the top.
