Your analysis is correct in as much as rates should not be raised in a failing economy. However, failure to raise rates after so much anticipation has dire consequences for the Fed and the dollar. If the Fed fails to raise rates then that is a huge loss of credibility and confidence. In short they would be admitting to all the lies about the economy. What would be the foreseeable consequences: loss of value in the dollar, loss of confidence in the banking system further withdraws, bitcoin and gold driven higher in a move to safety. It would be almost suicidal. Should be a fun week, remember "Jack be nimble Jack be quick" there is a burning candlestick.
