Not to mention software is one of the rare industries where, if you're not happy taking orders from the MBA PHB, you can leave and start your own thing. No other industry requires less capital to start your own business. The amount you can accomplish with spare time and your personal laptop is insane compared to the kind of capital other industries demand for their startups.
Anything where the business owner can create intangible products himself/herself (e.g. writing, design, wedding planning, whatever) has just as low starting capital required.
