Since this list is so broad it includes pretty much any professional activity, as a counterpoint, compare to Adam Smith, who had a lot more rigorous definition, and for who wealth creation can only happen when labour is applied to the production of useful commodities, or in the market making for such (crudely summarized). e.g. "curing disease" did not create wealth. Instead, he put physicians on the same level as house maids and clowns, in that they are unproductive in the strictest sense (although still necessary of course).
