Most likely you have either: a) already done manual labor (for yourself) or b) will and your parents may have shown you how in anticipation of this.
Or you have seen your parents do it, and have therefore seen them hold a hammer and through that learned how it is to be held and used.
I wonder if these people have never had any of the three happen. How rich does one('s parents) need to be for that?
I hate how liberals say it's because "they're dumb". No, it's legitimately the case that most of these people have unironically never held a hammer in their lives.
They're also probably just not that bright. Liberalism (especially of the neoliberal variety these schmucks represent the worst of) and the triumphal "end of history" really did a number on the western elites' intellect IMO. The walking, talking turds holding highest office across the west nowadays seem to have no self-reflection, perhaps no cognitive empathy whatsoever- and there's been no incentive for them to develop it.
