Why would we pay attention to the government statistics?

Why would we pay attention to the government statistics?  We could simply rely on the best non-government stats for:

1)      Unemployment  stats;

2)      Inflation rates;

3)      GDP;

4)      Total government debt;

5)      Total government unfunded liabilities.

Every government has an agenda –generally to make themselves look good.  If they can cheat of the stats, they look a little better.
