He now suspected that every human being who knew how high-frequency traders made money was making too much money doing it to stop and explain what was going on.

Thus the only Goldman Sachs employee arrested by the FBI in the aftermath of a financial crisis Goldman had done so much to fuel was the employee Goldman asked the FBI to arrest.

"Liquidity" was one of those words Wall Street people threw around when they wanted the conversation to end, and for brains to go dead, and for all questioning to cease.

The relationship of the big Wall Street banks to the high frequency traders, when you think about it, was a bit like the relationship of the entire society to the big Wall Street banks. When things went well, the HFT guys took most of the gains; when things went badly, the HFT guys vanished and the banks took the losses.

People who had lived without government were more likely to find meaning in it. On the other hand, people who had never experienced a collapsed state were slow to appreciate a state that had not yet collapsed.

If your ambition is to maximize short-term gain without regard to the long-term cost, you are better off not knowing the cost. If you want to preserve your personal immunity to the hard problems, it's better never to really understand those problems. There is an upside to ignorance, and a downside to knowledge. Knowledge makes life messier. It makes it a bit more difficult for a person who wishes to shrink the world to a worldview.

Reg NMS was intended to create equality of opportunity in the U.S. stock market. Instead it institutionalized a more pernicious inequality. A small class of insiders with the resources to create speed were now allowed to preview the market and trade on what they had seen.

The more money to be made gaming the financial markets, the more people would decide they were put on earth to game the financial markets – and create romantic narratives to explain to themselves why a life spent gaming the financial markets is a purposeful life.

The U.S. stock market was now a class system, rooted in speed, of haves and have-nots. The haves paid for nanoseconds; the have-nots had no idea that a nanosecond had value. The haves enjoyed a perfect view of the market; the have-nots never saw the market at all. What had once been the world’s most public, most democratic, financial market had become, in spirit, something like a private viewing of a stolen work of art.

A thought crossed his mind: How do you make poor people feel wealthy when wages are stagnant? You give them cheap loans.
