The obvious reason that US air traffic control has been understaffed for "a while now" is that, roughly a decade ago, the FAA caved in to political pressure to stop having so many white controllers by decommissioning any hiring practices that posed a risk of hiring white controllers.
This meant the size of the workforce froze, stressing the system.
That scandal exacerbated the problem, but there would still be a severe shortage had it never happened. The core issues, pay and grueling hours, predate that scandal by decades.
