I have had many different jobs. I was an amateur pianist, soldier, tutor, and research assistant -- along with few under-paying jobs. I dislike the idea that skill is "sold" with money. We should be able to help each other out and do what we love instead.
As most of you can relate to, when money--or fiat currency (as is the popular method of today)--is involved, people act differently. When you are a customer, you act harsher because your hard-earned cash is now being spent. When you are a service provider, you have to do anything to earn your money. The thing is, most of us are not strictly just a customer or a service provider. We are usually both. And that makes a cycle of emotional hardship for most of us. I have seen plenty of people in my field who release their stress by acting like an asshole to other service providers as a customer. And then that service provider will go to another service provider as a customer and be an asshole and so forth. I hate it. That problem is even worse in the Military. When hierarchy is involved, there is actual physical abuse happening. The worst thing I experienced in the military is that, when a superior orders his inferior to not sleep for 3 days, the guys who were told that would say the same thing for their inferior after as well. There were also the occasional "correctional" beatings.
I think most of us would prefer the Paleolithic period when people simply bartered -- even though modern technologies give us significantly increased quality of life. Not that I would give up dentist services and electricity and guns and houses and clothing and easy food, etc., but I hate this cycle of emotional and sometimes physical violence involving "money". Money is for people, not the system. So why are we making the world worse with something that we invented for our convenience and development?
So, I'd like to bring back what our ancestor did back in the old days. I am not sure today's capitalists will be annoyed by the idea of "primitive" bartering -- or rather, people will be able to use bartering to their selfish advantage. However, I'd say it won't hurt in general for us to do it. Let there be a diversity of exchange. We deserve that.
