What difference does it make if SBInet cost $1 billion, or $1.2 billion, or the real amount, $1.389 billion?
First and foremost, American taxpayers paid the SBInet contracts to Boeing. There is a big difference, exactly $389 million, between the first number listed above and the last.
For example, imagine what cities like Flint, Michigan could do to fix their lead problem in the water, or the salaries that elected officials in Ferguson, Missouri could offer its police officers so they could hire the best trained personnel available. Imagine the impact on public education in troubled school systems in Chicago, Baltimore, and other major cities. There are, in fact, endless ways that $389 million could be used to improve the lives of Americans.
The public has a right to know how its money is spent. Simple as that.
