Doesn't that pretty much describe the 2007-2008 financial crisis?

And every such crisis before it, and the next one too.

The crisis was 07/08, but the buildup was almost a decade in the making, does that count as short term?

the law in the UK is that material risk takers bonus pay over a certain amount (couple of hundred thousand) is deferred over 3-5 years and can be clawed back

Maybe the profit share is earned out over time? Otherwise I would agree with you..

If you think it's easy to game 30M in short term revenue, please try to do that in a large firm.

The risk/compliance teams would be interested in your strategy.

I'm a socialist/anarchist, they would never give me that opportunity :)

You could try this overall strategy in the stock market and see how it works out ;)
