I'd like to build and sell rapid prototyping machines as a way to decentralize production and put it in the hands of individuals. In layman's terms, rapid prototypers are 3d printers, aka fabbers.

There are many different rapid prototyping machines out there but I'm particularly interested in the ones that can print all the parts required for their own construction (duplicators). It's obvious that building, selling, or training people to use these devices are all jobs that are extremely vulnerable to the very technology that makes them possible, but knowing how to rapid prototype is a job like knowing how to build your own house, which will never be taken entirely our of the hands of those who seek shelter. The concept of a paying job itself is vulnerable because dollar bills have no nutritional value. As our jobs have been outsourced to third world countries and forced upon people who have no options, we are going to find we are in competition with those people who have no options; the people whose extreme poverty has thus far allowed us to de-value the goods and labor they make available to us. If this is to be the case it would be wise to prepare technology to allow us to be independent of an economic system that is going to come back to bite us. Grow food, make what you need, show other people how to do the same. Unfortunately this leads to the job that will never go away:
Arms trafficking: weapons manufacture their own necessity. If one army exists, so will another. How can peaceful, independent people realistically protect themselves against war without fueling it? perhaps by taking lessons from the Battle of Thermopylae. I think Einstein said "you cannot simultaneously prevent and prepare for war." People who are not under the umbrella of an organized military are taking their chances, like hunter-gatherers in the jungle. Can forest dwellers outlive the loggers?
