Today's picture was taken in South Missouri in 1940. It shows a blacksmith working at this anvil. It looks like he is beating on a plow.
Can you imagine if someone tried to have a blacksmith shop like this today? For the one guy working at the anvil, there would be two bureaucrats back in Washington making up rules to make sure he was "safe". Then he would have to hire two safety experts to make sure his shop stayed in compliance with the regulations. Then he would need two more people to make sure he was compliant with all the tax regulations. So, in the end you would have 7 people, with one doing real work.
