We have a Federal Reserve with a political appointee in charge determining the velocity of money in the United States. If you want to shore up reckless speculation, raise rates. The conditions that allowed this current crisis to happen start and end with the Federal Reserve. Look at the facts objectively:
There have been 5 major bubbles in the past 10 years:
1. Tech Stocks
3. Broad Market Stocks
4. Oil and Food
5. Consumer Credit
A bubble cannot form without an imbalance in money and credit. There was too much money and credit and it created artificially high prices across the board.
This is nothing to do with "Oligarchs". This is poor monetary policy.
