Does anyone think that the government (or, for that matter, anyone) can state with any degree of accuracy what the GDP is and by what amount it grew or shrank? I, for one, do NOT, and would be surprised if anyone could come within 1% of the correct number. There are simply too many variables, not least of which is the "underground economy" represented by the drug trade, prostitution,and other illegal endeavors. Then, there are the millions of people who derive a substantial part of their compensation from tips--think casino workers, waitres/waitressesses, bell hops, porters, skycaps, etc. So I would not be confident of any GDP numbers published by the government or by others.
