When major corporations and banks are sitting on boatloads of cash, even during a huge economic downturn, and given more cash to sit on... The fed can't hit their inflation target if the money isn't actually making it into the sector. But, inflation will eventually catch up. Nobody knows when, though.
Capitalism, as a whole, is dependent on the trickle-down theory. When that theory is a failure, you get an economy like India. The rich are extremely rich, and the vast majority of the population are very poor. Get ready. This is our future.
