It is called the U6. Yes it includes the retired and disabled as long as they aren't confined to an institution. Mother Jones recently called the U6, fittingly, "The Last Refuge of Scoundrels".
What brooks and others that tout this number fail to mention is that the reporting has always been the same. The U3 has always been "the official number", so it is ridiculous when Trump says the Obama Administration uses a phony number--it is the same number that has always been used! The gap between the U6 and the official reported number (U3) is somewhat larger than way in the past but this is because of many factors, the most impactful of which are technology and an aging population. But the gap is still smaller than it was in 08-09. See chart here:

Long story short, they want you to think it is all bad when it is not.
