Trade is an ancient human endeavour to procure enough food to survive. Today it is largely a transaction between a plastic swipe card using “credit” (which is basically just a promise of credit based on the promise of future credit, built on the foundation of nothing but more promises of credit between larger and larger entities called banks who guarantee their credit against more promises of future credit) and a large food retailer with the ability to drive down the buy price while charging consumers as they please for a trolley load of plastic-wrapped pseudo-food that is judged fit for human consumption according to lab testing.
Or maybe I’m being too cynical.
However there is still the ability to trade the old-fashioned way, and thankfully to pay a fair price for goods purchased, even if we can’t remove the deeply entrenched banks from the system. Barter, give thanks with produce, share and when you buy chose fair trade – either by buying locally, fairly priced products or looking for the fair trade certification on imported items.
