Does a caste system exist within the USA government and the Federal Reserve?

You can skip to the *** section to read my summarization.

Here is something I learned on wikipedia yesterday.

Ran across something called Lombard banking, a collateral loan system practiced by vikings inside Roman Empire borders. The Lombard tribe called it pawnbrokering and it was practiced because laws forbade Christians and Jews from lending money within their religion, but not outside their religion.

Jews lent money with gold and diamonds using something called a repurchase agreement. What amazes me is that this ancient repurchase agreement is the same as modern day Islamic banking which is still the same as the modern day pawning of goods.

Case example: A Christian goes to a Jew, buys a gold ring for $1.00, sells back the ring for more, $1.50, with the agreement that he will buy back the ring at an even higher price, $2.00. So the Christian gets $0.50 and pays back the $0.50 plus an extra $0.50. Plus you get the gold ring back so that you can sell it again with an agreement to buy it back.

It is an old form of what we now call derivatives: swaps, options, futures, etc. It is also an historical basis in Europe for Jew hate.

Going a step further I deduced a relationship between the expression "watch your back", "buy/sell back", "go back on a deal", "back out", "blow back" and "front" (as in "fronting someone money"). Invariably war and greed played a role in the expression watch your back, as in a warning to stand guard and be cautious of others as they cannot be trusted (their word or agreement or deal) in times of peace.

So if you were pawnbrokering, on either side, you had to be carefull of the buy back or sell back which is where the non-exisistant interest rate was thrown into the equation, and you had to make sure the otherside did not back out or go back on the deal. However, if you were a w****, you would front clients (i.e. to be truthful or to be upfront about the need to recieve payment before the service has been administered), hence the old idioms: Money before the honey.

So now I understand the birth of the expression "to be Jewed out of money" to be one synonomous with "being gyped". In these ancient times Jews ran trading houses and gypsy was a generic term for eastern born westward bound travelor or migrant. Since both were not Christian, both were permitted to lend money and certain services to Christians.

It's almost as if people create a caste system within their own society out of the fear of lending money. Which can bring about an even greater separation: debates, disagreements, fights and also war.

Does that sort of caste system exist in America?
