I'm pretty sure taking out a loan that you intend to default on is fraud, but making a contract with someone that you expect to be very profitable to you is not.
Are those committing fraud too ?
What, incidentally, about politicians who force pension funds to buy bonds "they like" by legal means ? (at least 200 politicians in current service are guilty of this)
These are US government bonds, by the way, if a default happens with them, the sort of organisation that will suffer the most is US pension funds.
