You are right, but I removed him to make the point that this is partly based on perception of the person doing the buying. Workin man this week is poor man next week and then some weeks he's richy rich. Do you want to capture all forms of this guy? None of this is rigorous of course but ya know we don't have a town full of 1 guy with a single budget. We have a town full of people with various and changing budgets, what kind of mechanism can be put into place to keep base finances workable in tight times while extracting more in good times?
