That's a nice analysis, and I agree with you about Marx. I'm a liberal too. Oddly enough I have a side-business that makes an electronic gadget -- think something like a guitar pedal. But I have to choose my battles very carefully to avoid needing any kind of capital investment to speak of, and the real barrier to entry is the knowledge that I've gained from being immersed in the industry. My entire physical capital is less than what an engineer's employer pays per year for a seat of a CAD package. A very big barrier that software developers don't face is regulatory approval.
