The NY Times has an interesting new blog called "Shifting Careers" that focuses on new career patterns. The blog oftens discusses working at home and personal businesses. A recent post called "How Do They Pay The Bills" talks about the financial issues and risks associated with becoming a "free agent".
One of the comments to the post mentions dual career couples who use one of the partner's corporate job to provide benefits and income while the other partner starts a business. We call this the corporate soho hybrid model, and discuss it in our forecast reports. This model is very common in Silicon Valley and gets around many of the risks associated with starting a business or becoming a free agent. It is also a model many mompreneurs used to start their businesses. We've also seen many examples of the partner with the corporate job later joining the other partner's business once it is up and running.
This approach is so logical it is bound to become more common. Of course, this option is not available to single people.
