A Hypothetical Power-Analysis of Foucauldian "Exchanges" of Material Goods

Form buying/selling barter gambling taxation charity theft
Privileged Position seller none the "House" the government the institution/the giver the thief
Unprivileged Position buyer none the gambler the taxpayer the giver/the institution the "mark"

1)  What "normative" conditions do these assignments of privileged and unprivileged status assume?

2)  What cultural forces can subvert those conditions and reassign status?

3)  Which of these exchange circuits compensate the unprivileged in one exchange by assigning them privilege in another?

Hint: if the subversion or compensation does not occur in this exchange system, might it occur in the exchange of people or of ideas?
