To see into the future it is always enlightening to look into the past. People haven't changed much for thousands of years. Philosophy and technology changes but atitudes change only little by little. As everyone knows there is a massive USA problem of debt. Not so long ago Athens rose to prominence as a City state. It had great wealth and power in the Eastern Mediterranean. With this sudden increase in power, trade flourished and many citizens became very wealthy. Nothing remarkable about that you might say. As the years rolled on the rich got richer and the poor got poorer. Sound familiar now ? To keep afloat the poor had to borrow more and more from the rich UNTIL many were so hopelessly in debt they had to agree to terms offered by the rich - namely slavery. Have people offered themselves on Ebay yet for say a year to anyone willing to pay off their debts ? I haven't heard of it but the situation is not far away I expect. I think you are now wondering what happened next ? Well, study and enjoy your history and find out for yourselves , because it may well happen in your country!!
