The truth is most white collar work, in private industry and especially govt, is bullshit. The whole nation could pull an Elon, get rid of 80% of their white collar headcount, and shit would probably work more efficiently. But that would leave a whole hell of a lot of people out of work. Our economy is mostly a Ponzi scheme, and many Americans (especially white collar workers) are just welfare recipients at the end of the day. But some workers/industries are better than others as far as actually contributing positively to America.

If you want to have an ethical debate about making bombs for sand people 10,000 miles away to kill each other, that is fine. But as far as being "America first," Congress spending $1 billion (or whatever) for American companies to make military shit to send to Israel (which they will actually use, which adds a tremendous amount of value to us for many reasons*) is probably a fairly solid economic return for us.

*Again, ethics aside do you have any idea the value of Israel using our shit in the field to test it under real world conditions is? We could be paying them to take and test run our shit and it would probably be +EV for us.
