We exclude a lot of people. This happens unconsciously and consciously, often with the best intentions, for example to manage risks. It can also be different. By looking at recruitment & selection and organizing work differently, opportunities are created for people who would otherwise not have their turn.
Meaningful work is work in which people experience autonomy. A company that works with a form of shared ownership makes use of collective intelligence. Running a company from the bottom up, by the people who work there. That is a goal for a solidarity economy.
