Did you really mean the US as greatest “benefactor” of WW2 (as in, helping others) or as greatest “beneficiary” of WW2 (as in, gaining from it).
Because it looks a lot like the latter since in helping others the US was mainly helping itself and that help didn’t come for free (for example, the UK only finished paying the debt to the US from that “help” in, if I’m not mistaken, 2012), plus the US gained its superpower status exactly from, as you pointed out, still having their factories and selling weapons to its allies.
