I think this is extremely applicable in inefficient third world economies, but I can think of a few reasons it might not be as applicable in a first world country like the United States.

    - Most basic skilled services already have many providers.
    - The startup costs for these services are significantly higher in first world countries.
    - The expectations of consumers are also (probably) much higher.

So, I want to believe, but I'd like to see some evidence of broader applicability before we leap to conclusions. That brings up another problem, though: this is so much harder to do in a developed country because it is prohibitively expensive.
