Agreed. I would also separate the arguments that "everyone should look at starting a business" from "everyone should look at working at a startup." The latter is a subset of the former. One's own businesses are a lot of work. However, starting a micro-business gives tremendous freedom, and I think this freedom gives folks a greater opportunity than anything else.

With a micro-business you can do the things you like to do and work on the problems you want to work on. Could be coding against technical problems, interior decorating, catering, or whatever.
