The Pentagon said that 
@SpaceX
 has saved the government over $40B. One SLS launch costs billions. One SpaceX launch costs less than $75M.

SpaceX President Gwynne Shotwell on SpaceX's $22B in gov contracts:  "We earned that. We bid it, we were the lowest price, best bidder, we won and we execute. It's not a bad thing to serve the U.S. government with great capability and products."

The people complaining that SpaceX's gov contracts were "wasteful" really have no clue what they are talking about.
