Chris Edwards of the Cato Institute testified at a Senate Finance Hearing on Tuesday.
Essentially, Edwards argued that the federal government has a "spending problem." Increased spending, he said, is almost entirely responsible for the last 5 years of high deficits. Therefore, we ought to get to the root of the problem and cut back on spending to get the deficit under contol. This is the same tack that Senate Budget Committee Chairman Judd Gregg (R-NH) has taken while advocating for drastic budget cuts.
