How much do members earn?
At this point, this is very much an exercise in speculation. But some approximate values can be expressed based on current incomes for technically specialized people. In the UK for example, at time of writing, a graduate with 2 years experience can expect to receive anything from £20-30,000 depending on which region of the UK and the particular company hiring. With the community requiring some money to exist and provide food, water, electricity, insurance and other day to day essentials and materials for the members en mass we can suggest a saving of 5000 to 6000 every 6 months. for each individual should be more than feasible. Providing ample reduction in normal fees for competitive contracts from the community, while also giving the member a large amount of savings from 10,000 to 12,000 per year. But finally also allowing the community to save an excess for future hard times.
** Addendum , having run a business now for the last 5 years I would suggest that excess amounts would be poured primarily into a treasury.
