I take the calculations of those "bureaucrats" than yours any time.

Common sense will tell you this, to much of a political football and its easier to point the figure at a boffin if its wrong.
There is a huge amount of extremely talented people putting their all into trying to solve this. A lot will be going way beyond what they are paid for and its very insulting to them to imply they are bumbling fools.
