The effect that numerous small inventions have on a culture over time are significant. Examples are the wheelbarrow, soap, the heavy plow, and stirrups.  

  Before the wheelbarrow, man was limited to how much they could carry and it was more labor intensive. After the invention of the wheelbarrow it was easier for man to haul small to medium heavy loads which then increased  society’s capital. 

Soap before it the Romans covered themselves in oil then scraped it off. After the invention of soap people did not get sick as much so then they could work more. 

Before the heavy plow it was harder to plow the fields that have more harder clay like soil. But after the invention of the plow it was easier to farm the land that had the harder clay like soil. Which then more fields could be plated so then there could be more people in the community. 

Stirup before the invention of it people used chariots after that they made it where you could only put your big toe in. Then they made it where it was on only one side of the saddle so you could only use it to get up on the horse it was harder to stay on the horse when you are going fast. But then it was made to where there is another stirup on the other side.
