The fraud and waste in government has grown over the last couple of hundred years to where it is today? To think that it can be eliminated in less than 4 years, is foolhardy!
It is the 80-20 concept.
The first 80% of the waste fraud abuse and evil will take 20% of the effort to eliminate.
The last 20% of the waste fraud abuse and evil will take 80% of the effort to eliminate.
That means the first 80% is totally doable in four years.
