Musk was the golden boy of the Obama administration. Their role model for the world on how we should all go green or feel ashamed if we don't own an ultra expensive Tesla car. All of this while behind the curtains nothing was being done to combat the growing global warming or the inevitable energy crisis, that awaits us after the petrol runs out.
So all in all this is quite typical. They give people a "discount" on their taxes, Musk does plenty of business, and the only loser is the budget. Meaning all of us.
