The market in america is due for a crash and here is why -   Lets start with Rome,   Rome was an empire and like all empires, they eventually fail and often for similar reasons.  

1. The debasement of currency. - The staple currency for the roman empire was the denarius. The denarius began as a small silver coin first minted in 211. It was mostly silver at the start and was literally debased until it was almost entirely base metals. America has done the same with it's money, began as gold backed, world war 2 and 
2. Overwhelming debt - referance the clock and the personal debt
3. Taxation rampant
4. Multiculturalism - not a strength, a cause for strife and cultural collapse

  What is going to happen - we are never paying that money back - the people who have saved money in this system will lose it all and debts will have to be erased   If you're unfamiliar with the term, it comes from The Old Testament, the Book of Leviticus, Chapter 25. A Jubilee in the Jewish tradition was said to occur roughly every 50 years. It was a time for total forgiveness of debt, the freeing of slaves, and the returning of lands. Pope Boniface VIII proclaimed the first Christian Jubilee in 1300.   Lupercalia conventionally starts with the founding of Rome (traditionally, 753 B.C.),   Etymologically, Luperci, Lupercalia, and Lupercal all relate to the Latin for 'wolf' lupus, as do various Latin words connected with brothels. The Latin for she-wolf was slang for prostitute. The legends say that Romulus and Remus were nursed by a she-wolf in the Lupercal. Servius, a 4th century pagan commentator on Vergil, says that it was in the Lupercal that Mars ravished and impregnated the twins' mother. (Servius ad. Aen. 1.273)   There priests sacrificed a goat and a dog whose blood they smeared on the foreheads of the young men who would soon go prancing naked around the Palatine (or sacred way) -- aka the Luperci.   Women were struck by goatskin thongs, thought to imbue them with fertility.    Goats are symbols of sexuality and fertility.   By the second century A.D. some of the elements of sexuality had been removed from the Lupercalia.   Sacrifice, which was a part of Roman ritual, had been prohibited since A.D. 341, but the Lupercalia survived beyond this date. Generally, the end of the Lupercalia festival is attributed to Pope Gelasius (494-496). Wiseman believes it was another late 5th century pope, Felix III.   However constantinople continued the tradition until the 10th century
