California Bob comments on Michigan Mike's Gravely Tractor Upgrade:
It is focus and determination like this that makes the world a better place. Our washing machines, dishwashers, cars, not to mention antibiotics etc., came from endless hours of obsessive work. That's not to say the originators necessarily benefit, themselves. Probably not a lot of correlation between usefulness of invention, and benefit to inventor. After all, the most useful items are antibiotics, clean water, power...but people have gotten wealthy off of fabric softeners and TV shows, and worse.
