The effect of metals speculation was to push up the prices that China had to pay to countries like Australia. This squeezed China. Once the speculative demand ended, all of a sudden the added production facilities that had been brought into production by the high prices went out of production again, and there was a glut.

Today, people are having to spend so much of their money, to acquire a house and to get an education that they don't have enough to spend on goods and services, except by running into yet more debt on their credit cards and other borrowings.

In China the largest denomination bill they have is 100 yen, and that's maybe $7. So here you have a whole economy working with only a $7 note as the largest denomination. The euro wants to get rid of the 500-euro bill just as the United States years ago got rid of the $1,000 bill because only the criminals used $1,000 bills.
