That video Esch posted reminded me of something that happened in grade school.

One year we had to do something similar to Young AmeriTowne that was called "Town." Each classroom in the grade would split up into teams and develop a "business." All the other students in the other grades would visit our classrooms on designated days, be given a fixed amount of scrip, and then permitted to shop at our respective "businesses." I forget what we could use the scrip on... in my classroom it was probably privileges and what not. (We had a bizarre system of credit that you spent to use the bathroom, get a drink of water, pay for a demerit, or go on a special lunch trip to Carl's Jr--this was where I learned about debt financing btw but as always I digress.)
To date myself horribly here, my group decided to sell sports trading cards. This wasn't the best idea but it also wasn't the worst idea given that it was 199X; I think we were all mainly concerned about getting rid of a lot of excess inventory we'd all accumulated over the years more than anything.
Our teacher at the time was dating a guy who would often come around our classroom and unbeknownst to us he was extremely into sports trading cards. When he found out what our wares were for Town he arranged to purchase all manner of cards at whatever price we named because he had access to the scrip bank through his personal relationship. Since we were little shits we named (what I recall as) absurd prices for our cards, or at least prices that could never be supported by the vulgar market in which we operated. Since these sums were utterly irrelevant to our buyer he gladly paid and we more or less crushed our classmates in this
exercise of bourgeois propaganda.
Not only did I buy myself out of using the bathroom credit hell with this endeavor but I learned a valuable lesson about the ethics (or lack thereof) in for-profit markets.
