They are the ultimate bubble, fractional “lending”, Ponzi scheme, etc.
I think the market is so controlled and manipulated that it no longer behaves as one would expect based on history. For example, when a lot of selling starts to happen, computers shut down trading. This is an unnatural process that on the surface appears to be a good thing but surely there are many unintended consequences.
The other thing is the feds manipulation if the currency and the free money that the banks can take and invest in the markets. Everything is artificial now, and I think at the right time, some group of people has the power to flush it. Maybe right before the election for example like what happened in 2007...
