The price of a loan is the interest rate. If you have a halfway decent credit rating, you can drive often off the lot with a new car at less than 1% interest rate. And the fact that people with "sub prime" credit can get a car loan at all is a sign of lower borrowing cost. In the old days, a jobless single mother wouldn't be able to get a car loan at any interest rate.
final drop was the conquering of Jerusalem
You need to check your own history. Muslims had ruled Jerusalem for 400 years before the First Crusade. It was a prosperous city of Muslims, Christians and Jews.
The Crusades stand as one of the great atrocities of European history. The massacre of Jerusalem. Documented cannibalism at Antioch. The betrayal and sacking of Constantinople. And they accomplished NOTHING. All of the Crusader states fell in less than two hundred years.
HOLY MACRO!
