I don't for a minute believe that the SEO folks outsmarted Google's engineers.
Although people have tried to make the financial system more resilient since the 2008 crisis, it’s really impossible to say how well those measures will hold up until they are really tested, which isn’t a very comforting thought. It’s very unlikely (in my opinion) that things melt down in exactly the same way as last time, but there’s nothing to say they won’t find a new and exciting (slightly) different way to melt down. Financial engineering isn’t the only thing that can cause a financial crisis.
It happened with sub-prime lending that ended with the 1008 crash. I do not know whether it is a significant factor with private credit now.
Financial engineering refers to the creation of complex financial products (usually derivatives) using techniques from financial mathematics[1].
Predatory lending is just lending to people who can’t afford to borrow. No engineering of any kind involved.

It's not like the government has been carefully introducing new, strict regulations on the things they were doing that got us into the crash once we've recovered from it. We just...let things stay as they are. Because half of Congress is white-knuckle gripping the steering wheel trying doggedly to keep us pointed toward the cliff, and the other half is dithering about wondering if it's too rude and partisan to gently take the wheel and try to turn it away from certain doom.
