1) Lobbyists 2) Tort 3) The Federal Reserve / federal banker insider system
The lobbyists are powerful because of what they can buy, because of the nearly total power over the economy that the Federal Govt. possesses. If the politicians can't dictate economic policy, then buying them is worthless.
The desperate need for tort reform is obvious.
The Federal Reserve has failed, basically across the board over the course of its entire history. It has created an economy dependent on one bubble after another. It has devalued the dollar by 97% over its history, and particularly dramatically since the 1960s. The dollar used to be regarded as being "as good as gold," that's a bad joke now. It is currently, intentionally, inflating massive asset bubbles with trillions worth of debt monetization ("QE") because it stupidly thinks that's how you create prosperity (or they're really clever and intentionally trying to crash the economy). It has to be abolished, and the US monetary system has to be returned to a sound basis, rather than relying on dollar devaluation to fund the government (ie we need strict balanced budget laws).
