The Brady Bunch was pretty mustachian. They crammed six kids into two bedrooms before carving out the attic for Greg. They shopped at Sears, spent nothing on clothes, drove modest cars even by early '70s standards, never ate out, took only the occasional vacation, and had just one TV, which they upgraded from black-and-white to color at one point. They also spent nothing on yard maintenance since it was artificial turf, which was always a joke until the 2000s when it actually became an option in places like FL, AZ, and CA. Clearly they were MMM trendsetters.
Admittedly, they ate red meat every night, which must have been pricey, and having an indentured servant sure helped, but they seemed to have their MMM priorities in line.
