Barracuda,
You make valid points on the industrial farming system, but note that I said "As long as they are not taking away from others by doing the extra work, why not?". I was simply trying to point out that some people are more driven to work and produce / create something valuable. And it is possible to create valuable resources with work and creativity, without hurting anyone, and even helping the collective good in the process.
For example, take Paul Stamets, the famous mycologist (I hope he is getting more famous at this point, at least). He has several business and also holds patents. Generally I disagree with the intellectual property system, however I would not begrudge Mr. Stamets the extra income he may earn from those patents because I am confident that his intentions are in line with the common good of humanity and the planet. His process of accumulating resources for himself has a positive effect on the planet as a whole, therefore I believe his businesses should be encouraged.
I think that many people who consider themselves leftists of some variety (not anyone involved in this conversation) should examine how much their ideology is motivated by envy, jealousy, and laziness. Because these are some of the main negative stereotypes of the left, and it is a real drag when people perpetuate them. For example, in Greece there is a taxi syndicate / union. While I generally support unions, in this case I think the regulatory state is being abused for the benefit of a few people.
I don't see any reason why ANYONE with a car should be prohibited from working as a taxi driver, provided that they comply with some reasonable regulations to protect their customers. Now, there are a limited number of taxi licenses and this results in artificially high compensation for people who hold those licenses. I don't think that this is fair, because consumers pay more, and there are very many unemployed people who might be able to scrape by using their car as a taxi. Just because someone bought an expensive taxi license doesn't entitle them to have a relatively easy job providing a luxury service. Or at least it shouldn't.
Also, you said:
There are almost certainly far many more individuals who would like to work as farmers than there are jobs for those people.
I have to disagree with this. The main impediment to implementing an ecological agricultural system is that it requires many more laborers to replace all the mechanization/chemicals and keep up with the demand for food. Generally people do not want to work in agriculture because the work is very difficult. It is basically the least secure work that there is, even with subsidies. It is fashionable to express interest in farming ecologically, and this is a start, but on the whole it is not happening. At least it is not happening enough to have an impact on the agricultural field.
So when you say that many people "would like" to work as farmers but there are no "jobs" available, what you really are saying is that many people like the idea of being a farmer, but it is too difficult to make a decent living working in agriculture. I mean, of course many people would like to own a farm and be a farmer. Owning a farm involves owning a lot - land, equipment, buildings, etc. Almost all people who work in agriculture are not farmers but laborers. The self sufficient farmer is an extremely rare species, and any of them will tell you that it is really difficult work.
So coming back to the topic of this thread, I would like to suggest that ecological farmers should have (be allowed to accumulate fairly) more money than taxi drivers, because they work harder and do more to support the collective organism. But hey, maybe I'm biased.
edited to add:
On second thought, that would never happen, ever, so what is the point of even suggesting it? Because this is a "should" conversation with very little connection to the real world, and is basically just an intellectual pissing match.
If I were to say, "People who work more or work harder should have more money than others." there would be a flurry of objections about how people who accumulate wealth must necessarily hurt others in the process. And I do not agree with this. I agree that most money is accumulated by exploiting others, but I think it is possible to create and accumulate wealth in a way that doesn't hurt anyone and actually helps the common good. So I think that is what this conversation is really about. Mac, would you like to comment on that?
