What do you think of this business model?

The link below is to a youtube video of a family machine shop business in Texas. You get to watch the second, third and fourth generations working side by side in the same building from 81 years ago. Nothing fancy. Nothing special. Just generation after generation learning from the one's who came before to continue not only a business, but a lifestyle that many might envy. For those of you who come from multiple generations of surveyors, would this be anything like the story that could be made of your business?
