Honestly, the craziest thing to me was seeing the largest corporations in America borrowing money they didn't need since it was so cheap not to.

In terms of consumer-facing financial services, having now worked for a fintech startup, just understanding the sheer extent of middlemen that purely exist just to borrow money at X% and lending it to the next link in the chain at (X+Y)%.

With the end of ZIRP, the hurdle rate for these kinds of firms exposes the sheer unsustainability of these lines of business. And I'm for it.
