>the people who work those jobs are usually struggling to make ends meet You are omitting the large swath of government and civil-service type employees - cops, firefighters, transit workers, utility field workers - whose base salary alone avoids "struggling to make ends meet", but they still want that overtime because time and a half or doubletime at their income level is quite lucrative, plus it helps to spike their eventual pension amount (although lawmakers are slowly wising up to that and cutting off the opportunities for new hires, although they can't change the deals the current workers already negotiated).
