One of the main factors which contributed to the Stock Market Crash in 1929, when the very loose regulations related to margin orders.
In financial terms, margin in an instrument which consists on depositing a collateral with a counterparty (generally the broker) to cover some of the credit risk that the depositor places to that counterparty.
In the 1920s, the mandatory requirements regarding margins were not very strict, and brokers asked investors to put in a small fraction of their own money. Leverage rates which measure the proportion of debt, reached 90% with a high frequency. Nowadays, the Federal Reserve has established the limit of 50%.
Back in 1929, when the stock market started to contract, many investors received margin calls. They had to hand in more money to their brokers, because the amounts required before were not enough and if not, their shares would be sold. Many people did not have the extra margin amounts required, their shares were sold and the market declined further. This generated more margin calls and more declines. This is why margin calls were one of the causes which triggered the Stock Market Crisis and, in turn, the Great Depression in 1929.
Farmers faced tough times. While most Americans enjoyed relative prosperity for most of the 1920s, the Great Depression for the American farmer really began after World War I. Much of the Roaring '20s was a continual cycle of debt for the American farmer, stemming from falling farm prices and the need to purchase expensive machinery. When the stock market crashed in 1929 sending prices in an even more downward cycle, many American farmers wondered if their hardscrabble lives would ever improve.
They were different because they were based on one god
Other laws in other regions were based around the idea of multiple gods so there were laws for various gods, agricultural, judicial, and similar things. The ten commandments were based around a single god which usually meant that it applied to everyone equally since they weren't followers of a whole pantheon and their differences.
