There is actually a nice little loophole that some of the big investment banks use. They can borrow money directly from the fed at a rate that is lower than the rate of return for t-bills. So they borrow from the treasury, buy t-bills then when the t-bills mature they pay back the fed and presto, instant free money. of course we the average person do't have access to this.
