They keep giving contracts to SpaceX because that’s the way the budgets are mandated from congress. They have X amount of money to distribute. Everything goes to generally the lowest bidder, and because there are only a handful of options, they have to keep using one contractor to produce their parts because it’s even more expensive to keep switching.

So drop the attitude. Usually the worst bidder gets the job, and it ends up costing more money after everything is said and done.
