and we all depend on people we've never even met we depend on all kinds of specialists we never even see making our clothing building our houses and getting us food and that's where i come in three i'm a farmer growing my own food helping to feed the city nearby folks think i'm independent for instance the other day when i  rode into town with a wagon load of vegetables i met two old friends tom and jane they think i'm the most independent man they ever knew thought of jane said they were going to be farmers as independent as you well now wait a minute just raising your own food isn't enough i'm not independent i depend on lots of people for instance today i'm depending on my show maker to fix my shoes up all you young of men in the mines and it forges helping grandpa did open the earth for planting the see and make things grow even more than they needed for themselves and that's when they began to depend on even more people to see the work was hard because the tools were clumsy reaping was an easy with a short handle one of the other farmers in the valley knew how to do a good blacksmith words told grandpa took some of the food he had left over to trade for a better tool it's just down the road there there's a man a farmer with a blacksmith shop still make good tool to seed my hand and help me raise the better this part time blacksmith promised to make grandpa a lot to handle size for some co trading that way grandpa could spend more time in farming because he didn't have to make his own tools not a part time blacksmith made good tools because he didn't have to spend so much time at farming by depending on each other they could speed with the new size grant park a swing wider and stronger when cutting down his grave the better the tools the more we can do and the better we and do it well before long so many neighbors w fields and get more out of the soil well better tools meant bigger crops so some people could eat without growing their own food they could do other things that made it easier for the people who were still farming for instance they knew that other specialists were busy making shoes for them or the  man who built it all i'm so grandpa and the other farmers and the cobbler and the blacksmith got better houses and better shoes because a specialist does a better job than the people who specialize live near each other by the banks of the river where the water wheel could give power for machine small town grew up if you think about it you'll see that's what towns and cities are places where specialists work and trade yet people who trade with each other depend on each other the cobbler made his own shoe the carpenter built his own house but each did only a part of getting his own food clothing or shelter the town grew bigger and bigger and bigger it's like a tree growing that starts from the roots like we started from the soil the farmer killed as the earth gave more we were able to grow away from the soil just the way a tree grows away from the roots way that the tree grows up out of the ground the fizz the way that the city grows out of the none of them gets his own food or clothing or shelter all by himself yes we've been able to grow farther and farther from the soil but as i keep saying man always has to eat it's only because we have powerful tools like my tractor that we farmers can grow enough food for all those millions of city specialist cobbler so he could spend all the time they can shoot the cobbler made the whole issue the form of the soul of i am the offer and he knew of the man who wore it but it's different now with all our cobblers work in factories and they they are a different kind of specialist each of them makes only part of the shoe and it takes hundreds of people just to make one shoe but these hundreds can make more in a day than the cobbler could make in a lifetime that's means i'm depending on hundreds of cobblers for just one pair of shoes three at these factory specialists make all the shoes for people they never even save people i depend on people in all walks of life for instance the fishermen bring it in their catch their scaly gold i ships are in the  be bringin in the crops if they weren't bringing in the fish supplying not only me but the other workers i depend on like the workers in the clothing factory turning out clothes workers whose job is divided among specialists the kansas plains to feed the people i depend on miners and workers in the machine factory and lots of others you see taught me with the tools we have today farmers all over the country can produce great surpluses these tools get their strength not only from the arms of a man but from cold and gasoline and electricity and men have to spend their time making the tools for only a few made grandpa's act or decide thrift tool like my tractor you need minders who spend all day digging out tons coal and iron we need factory workers will mold that are into shape and put it together to build tractors for farmers all over the country or get on the trac just for me so you see all these powerful tools help me to produce more food so i can feed the people who make them in the way i do it all work together to deliver the goods we'll all work together to deliver
