It's actually a great slogan because most people can look back to a better time. So what would this be for you?
I guess I'd look back to the days when labor unions were strong and fought for a living wage. I remember my dad working in construction. The Carpenter's Union made it possible for him to buy a nice home in the 'burbs and raise six kids. The Union is mostly gone now, and a carpenter's wages have gone way down.
Of course the person who used this slogan could care less about unions.
