From each according to his ability to each according to his needs. Paraphrased well enough?
And we do not have to go into a doctoral thesis to see how wrong that is, not in theory, but in practice. it has always failed and will always fail. man is not altruistic.
Did your family operate and succeed using another strategy?
For a family its "from each as much as s/he is willing to give to whomever they are willing to give it to". Helping your family is a choice, and it is not altruistic since they share your DNA and you are helping in its preservation and spreading.
I disagree about the "man is not altruistic" thing, man is not 100% altruistic, and man shouldn't be. Humans have both selfishness and altruism coded into our DNA, our brains contain structures that inspire empathy, altruism, selfless sacrifice, as well as greed and hate and more... A society is more powerful then an individual, and psychopaths don't form societies. But pure altruism is exploitable and leads to stagnation and failure, just as pure selfishness does. We maintain a balance of altruism and selfishness.
Your debate and Dr. Guy is interesting, it is a fundamental issue of societies. You both agree that if you take materials and build something from it, its a product, its yours, you created it. But what of the land, the raw materials in the earth, the air and water around us, etc... who owns them? Do they belong to everyone (mediated via government ownership)? do they belong to an individual?
My take on it... in the abstract they belong to "everyone" (aka the government)... but the issue is what happens when the government SELLS it? Well, if the government sold it, then it now belongs to whomever the government sold it to. That person invested time / effort / money to buy something at what the government deemed a fair price, if he later finds diamonds in his plot of land, it is his to benefit from.
What the government COULD do is lease a land, or sell a license to use its land for specific things instead of selling the land itself. For example, the government could sell agricultural rights to a land, while maintaining mineral rights. This will diminish the amount of money the government would be getting for the land. The problem is that people want to sell their cake and eat it at the same time. Either the government is SELLING you the land (in which case it is YOURS, the land belonged to EVERYONE, the government is a PROXY of EVERYONE, EVERYONE SOLD that land to YOU via their legal PROXY. The land now belongs to YOU, not to EVERYONE), or the government could be leasing you the right to live and commercially develop specific things on the land but not others.
Now, SHOULD the government, as a proxy of everyone, sell land? or should it only lease it for specific use while maintaining other rights? I am not entirely certain, I think there could be a strong argument for merely leasing it. but it means that the land is PRICED ACCORDINGLY! furthermore, I am concerned that it might harm the economy.
Things like air, water, and land, if "owned by everyone" fall into the tragedy of the commons. Pay per use is fair for those, the problem of course is when the government is promoting unscientific hogwash as fact... if someone is emitting lead particles into the atmosphere, its pollution and degrades a "common" resource, but if someone releases carbon dioxide? thats nothing, plants eat it right up and it causes no harm to the environment (humans account for 3% of yearly global emissions, half of which is due to industry, half of which is due to breathing, and carbon dioxide was never shown to have anything to do with global temperature).
A problem of strictly metering out the use of commonly owned things like water, wildlife, land, air, etc is that it is stifling for an economy and causes economic stagnation which we can ill afford. Some might look at it and say "this is essentially everyone giving free money to some rich guy"... the problem is that "some rich guy" is the guy who is actually building and running the foundation of the economy without which society doesn't work. It is not "free money", it is money (or actually, property... air, water, land, etc) handed over in exchange for goods and services (electricity, cars, steel, etc) without which nobody would have any of our modern comforts.
Land taxes are essentially the way in which the government is "leasing" the land, eminent domain and mineral rights are a function of the lease. On the one hand, since it was understood by both parties before the "sale" that those are a given, that the current "sold land" was misnamed and is actually "leased" land under a different name. Because truly sold land should be exempt of land taxes, eminent domain, etc. On the other hand, since the government explicitly said it was SELLING and not LEASING the land to people, then it has been engaging in fraud... Tricking people into thinking they bought something when in fact they only leased it, selling it and then charging rent / evicting you when they need it is not acceptable.
The transition from a dishonest system we have now to an honest system where you call things what they are will be painful, you will have to resolve where it is between those two positions that we settle. did the government really sell, or didn't they? I think the solution is somewhere in between, but it bears more thought.
PS. OMG! I never figured this one out before right now! I have been reading your argument and thinking how right both of you sound, but how can you both be right? and then it finally clicked and I came up with the above! This is awesome, I finally deciphered land ownership!
