Here is another paper that echos the opinions of most on this sight. It’s certainly a biased paper, but it’s interesting none the less.

The issue I have is the last part of the paper, with the proposed solutions. A lot of that is government meddling in “private” money, which I am not a fan of, because ultimately it’s up for the free market to decide (at least in theory).
