godislove: You should focus on INTEREST, that is the real transfer of wealth in the monetary system. The average worker pays nearly half their wages to interest, most of it embedded in their normal consumer goods. The top 10% are the net recipients of most interest payments.
BTC can not eliminate interest, in fact without inflation it would raise interest rates, so BTC is no good but not because of it's transaction fees. Freicoin is exploring a solution to lower interest rates using a demurrage mechanism on coins first proposed by economist Silvio Gesell.
Impaler, it's not only interest, but rent, insurance, and fees that eventually shift society's wealth to a single small class. These are all incomes that were not as a result of contributing something productive to society. They are called the "FIRE Sector" because they burn societies down. They should be outlawed because they are the new forms of indentured servitude and debtor's prison, or they should be issued only by the government and the government derive it's only income from these sources. Taxing the land value of real estate is an example of doing this, but it is called a "tax" instead of "rent" or "interest", even though it is all the same. Loans enable city dwellers to bid up the price of houses way beyond construction costs when really it is the city's existence that makes the land valuable and therefore the city should tax ("rent") out any potential extra value in the land that banks want to get by interest. So "rent", "taxes", and "interest" are all the same thing: a duty being paid to a feudal lord who does no work for society. Loans to finance useful industry (rather than to simply bid up asset prices) is completely different, but even then it should be a partnership between the loaner and the loanee (no collateral), who are mutually interested in succeeding and mutually failing if the enterprise fails. This type of loan has another name: equity investment as a shareholder. No bank bailouts would have been allowed if we had viewed the banks as at-risk partners in the loans. The banks would not have allowed us to bid up the prices beyond sustainable value in the first place. But excessively large houses do not add productive value to society so should not be capable of securing a loan anyway. And city houses do not derive their increased value from the efforts of the previous home owner, but from the success of the city as a whole and the profits thereof belong to the people of the city, homeowners or not. The free market does not care about these things, which is why the free market naturally causes society to polarize to favor the few who are faster at planning ahead than others. But planning ahead to defeat others is not adding productive value, except for eventually decreasing the number of less competitive children if the government stayed out of the way and let the economic slaughter of the middle class proceed. This is why democracy wins: it steals wealth and legal rights from the powerful via a 1 vote per person populous, thereby increasing the number of people and commodities to engage in war to defeat other systems of governing. The primacy of the individual in capitalistic thinking is just as factually wrong as thinking the gene is the seat of evolution. Evolution is occurring at all levels at all times from gene to genus. The "Selfish Gene" theory has been proven completely wrong. Likewise, a strong society is made by working together at all levels, even worldwide, not by pure ideological selfishness at the individual or family level with the hope that the invisible hand of a free market magically solves all ills by some sort of emergent intelligence arising out of chaos.
I do not agree with Gesell because savers are then penalized for the interest crime of non-production loans. It seems like simply giving the 5% annual fee to miners is...excessive...and would produce too many miners like too many banks. The demurrage has the same net effect as inflation and loans the government will never pay back, differing only in how the money is redistributed. Certainly "to the masses" with demurrage is better than "to the banks". Again, you can call it a demurrage, fee, tax, interest, or rent, but it's the same thing: someone is getting something from society without adding value to society. Again, it seems to much of a gift to the miners.
Wouldn't it just encourage potential loaners to buy assets and then loan out the asset, at "interest", then reinvest the proceeds for more assets? That's called being a landlord and collecting rent. Same thing as interest, just a little bit more work. Eventually 1 person owns all the property. Renting is rare these days because interest at least allowed us to eventually own the house, and also because tax deductions and low interest rates encouraged the wasteful bloated loans. See Michael Hudson's blog and this page in particular for the things I am discussing etc:
http://michael-hudson.com/2001/04/the-mathematical-economics-of-compound-rates-of-interest-a-four-thousand-year-overview-part-ii/I am going to write a post with more specifics on how to enslave your bitcoins (or other coins that have Script capabilities) to stick to a basket of commodities. I prefer to leave it up to government to outlaw loans that require collateral (which is an indentured servitude or debtor's prison for your valuable asset), and the other things I mentioned. This is an old Anglo-Dutch style loan that I believe the German system fights against and it has been said to be the historic source of German economic success.
