Aside from fixed costs, the military and national security are the biggest chunk of the budget. Therefore it is especially valuable to cut waste and unnecessary systems there. If the F136 is not a valuable addition or replacement for our military, then it should be cut.
Personal note: I own some GE stock. My son is in Special Forces and doing his 20.
Out of curiosity, do you consider DHHS’s $875 billion budget a fixed cost?
