The book Fault Lines: How Hidden Fractures Still Threaten the World Economy makes a claim to that effect, that US government created some unfortunate incentivizes towards risky credit. It was of course not the only problem that led to the 2008 GFC, but it certainly was a part. I recommend the book, it was detailed and has a global focus, as the author was the Chief Economist at the IMF for some years.
