We invest a whole lot in airborne ops, which very few units actually ever use in combat. And IMO, even the few times we have done airborne ops in the recent decades have been for show, and/or because there's a prestigious badge associated with it.
I think there is still a legit reason to have airborne slots and airborne school, but far fewer people need to be on airborne status. We could save a whole bunch of time, money, energy, and injuries by greatly paring back airborne billets.
