Hi Galen, years, many years ago I participated in a time bank. In principle the issue is very simple, for example I work for an hour and in return a plumber fixes me a breakdown. Everything is measured in time; in fact it is a barter of time: mine in exchange for yours.
This time bank went bankrupt, yes, it is possible for a time bank to go bankrupt. It turns out that the person who worked in the office, who was in charge of contacting those of us who belonged to the time bank by phone, was also dedicated to phone erotic phones, leaving a large debt.
This is my unique and curious experience in a network of "favors".
Bartering is a good way to get what we need and I think builds a good community spirit as well. Of course, human nature can tend towards greed with some people so there's always someone whose there to ruin the process by cheating others in some way. Typical human behaviour.
The barter idea is very good. Then we are the executors of the idea 😰. Greetings.
