The notion that low barriers to entry (via low cost or free online office management tools, open-source software and Internet connectivity) enable anyone with a laptop, a cell phone and a good idea to become an instant tech entrepreneur is one we hear often in tech circles.

But what we don't hear or talk about is the fact that the new innovators fit a very narrow profile. They mostly come from more affluent backgrounds, are well educated and are rarely minorities. Many have gone to well-known business schools and colleges and fit comfortably into the mainstream business culture found in places like Silicon Valley. The obsession with hiring engineers and other employees from top schools at companies like is Exhibit A.

It is no surprise then that much of the gadgetry and Web services leaping from the minds of talented young innovators are geared toward young, well-educated, affluent white kids -- people just like them. When was the last time you heard of a groundbreaking tech product targeting seniors, the disabled or young black men?

Not only does this myopic approach create a design bias toward social elites, but it also relegates a large percentage of the population to the role of passive consumer of products and services they may not be able to afford or are unable to use. In a society where the pocketbook rules, so go the innovation tools.

And even when a genius residing in an urban ghetto or poor rural enclave does have an amazing new solution, he or she will likely never make it to Stanford or the doorstep of a major venture capital firm due to cultural barriers and a lack of connections and capital.

The issues that matter to those in low-income communities (e.g., crime, jobs and housing) are in most cases overlooked by the best and brightest. It's a tremendous lost opportunity to change the world for the better, and to empty another stream into the river of creative possibilities.

Fortunately, a younger generation of innovators has taken up the mantle of social innovation -- developing new tools and services for the social good -- everything from the Web-based granting of money to the needy to mobile phone banking for the unbanked.
