God forbid people save up a bunch of money and decide to not work for a year or two.
God forbid people have health issues that keep them from working.
God forbid people lose their job, struggle at finding a new one - not because they're incompetent but because they're terrible at job hunting. Or because the job loss triggers mental health issues (which you can't get addressed because you don't have a job and lots of mental health professionals either don't touch anyone on insurance period, or they don't touch people on the subsidized healthcare plans.)
Employers: "WE CAN'T FIND ANYONE TO WORK FOR US!"
Employee with a 2.5 year gap: "Uh, hi?"
Employers: "Not you."
