The recent trend is about atomizing plaintiffs. Not many people have the financial resources to bring a case on their own, and lawyers tend not to bring contingency fee cases for a single plaintiff without multi-million dollar damages. Her

The point I'm trying to make is that compartmentalizing things is good, because compromise happens. Don't bank where you browse and email.

Yeah, but you can keep a separate computer exclusively for finance, medical, etc. A Raspberry Pi 3 is like $40. You shouldn't be doing banking on the same device you use for generic browsing and email. It's really strange to me th

Agreed, financial market structure is often intentionally obfuscated by incumbents. The worst public example is undocumented equity order types [1]. The Fed's monetary policy models are another story. If you drill down on the inter

If you step through the arithmetic, you see that a 5% haircut can take you to 20x leverage. It's a geometric series. That means that investors' internal risk limits are the binding constraint, not repo haircuts. It's another
