There's a few episodes that actively showed gow much they struggle. Like one of their biggest vacations is going to a waterpark in a car that has the heater on full blast so it doesn't cook the engine. They only eat super cheap food and mystery meat. They lived in a camper because they could barely afford to get termites removed. Hal has no money to go to a dentist. As soon as hal lost his job they are cooked. They lived paycheck to absolute paycheck. They never pay all their bills. I would say they struggled a lot. They struggled more than al bundy.
