Looking out our kitchen window I am struck by the crazy hard work of the travelling market traders, many of them fairly old, and none of them young.
They get up damn early in the morning to get prepared, travel to a new market every day (shifting between some 20-30 locations each month), set up the numerous take-down stands for products, set up the stalls for shelter, and then stand up for a full day (which is a killer for anyone) selling stuff, regardless of weather. Then put everything back in their trucks and tomorrow they will be at a new market place, perhaps even another city. And in between all of this they need to handle import/ordering of goods, book keeping, taxes etc, etc, like any other business owner.
They work harder than most people I know and yet they pretty much gain no respect for it. They are hardly even regarded as business owners.
