He is basically presenting a variety of charts and data that indicate the expansion in asset inflation (stocks) has a direct correlation to central bank intervention and increasing government debt despite flat earnings and disproportionately slower GDP growth and lower labor participation rates.
He also refutes, with data, the Fed's public position on "how their actions don't contribute to income inequality" and how their policies are encouraging and supporting speculative risk taking in order to keep the asset bubbles going.
The main takeaway is that central banks are actually causing the very problems they are being hailed (in the media) as heroes for "fixing" with their flood of liquidity and low rates. Their forecasts for growth, unemployment and interest rates are historically inaccurate. The markets and economy are very vulnerable if the Fed loses control. They could not prevent the March correction (they had to take extreme actions to reverse the fall), and he posits that they won't be able to prevent the next one either.
His technical analyses and honesty are laudable. Well worth the hour of time invested IMO.
