Furthermore by honouring treaties and standing up to bullies the us is gaining a lot of soft power. As a european i want to see more american products in europe and i most certainly will be a strong supporter of your country.
And what happens if we stockpile munitions and don't use them? They age, get destroyed and replenished. The military is continually burning money to keep its stockpiles up to date anyway, and if we're sending stuff to Ukraine before it expires, that accelerates the replenishment, but I'd argue that it's better than the alternative.
Taxpayers, aka citizens, foot the bill in both cases
Oil producers and cartels raise prices because... money's being printed. Because Biden shuts down new pipelines, slows oil leases, is hostile to energy production. Demand craters because of lockdowns that don't work... then ramps up because the world tries to return to normal after a "pandemic".
Almost like an increasing demand with a dipshit anti-energy President is going to have disastrously bad results.
Seriously though... the problem isn't "evil companies" doing shit like making money (how dare they!). The problem is multifaceted.
Did you have an issue when companies closed at record levels because of bad decisions that caused the slowdowns? Or were you cheering because those companies got what was coming? do you think that the surviving companies don't deserve profits after years of losses?
Edit: if the equipment is new then the 1$ spent is basically a subsidy for the local weapons industry and the workers building it.
If you give someone else a bow and arrow, in exchange for an IOU for $1 for the arrow and $100 for the bow, you get your money back by collecting on the note. (Now, its true that Lend-Lease allows hiring US contractors for reconstruction as an alternative to direct repayment, but, how the money gets back to the US isn’t a mystery.)
If the able do not help when they are able, the unable will see and know.
And there may be a day when the able become unable and the tides turn.
