Conrad, your 'FREE paradigm' seems to emphasise the importance of access to minority groups such as the poor and those who drink heavily, but I'd like to know how your model includes other minority groups such as the disabled who might need special access not provided by a field. I'd suggest that this group is at least as important as those who live on a low income or those who choose to drink a great deal, and in fact they probably comprise a large percentage of poor people.
