It allows us to move objects with the minimal amount of friction.
Would you rather drag an object or pull it on a cart?
When you have wheels underneath the object your are transporting, there are only a few points touching the ground (the wheels). Therefore, there is less friction created when you pull the object. When there is less friction, there is higher efficiency.
There are, of course, other ways it makes life easier, but that is one of the main ideas.
Hope that helped. ;)
i agree with the above answer but i would not say a wheel and axle is the main point of simple machines and their efficiency

What are the functions of a wheel and axle?
A wheel and axle's main function is to make moving objects easier and less stressful on the operator.
How is the wheel and axle and pulley similar?
Both the wheel and axle and pulley are simple machines that involve rotation to make work easier. The wheel and axle use a wheel that turns on an axle to help with the transfer of force, while a pulley is a wheel with a groove that can rotate on an axle to lift or move objects by changing the direction of the force applied. Both machines multiply force and make work more efficient.

What is the outer ring or cylinder of a wheel and axle called?
The outer ring or cylinder of a wheel and axle is called the wheel. It is designed to rotate around the axle, which is the central shaft that supports the wheel and allows it to turn. Together, the wheel and axle form a simple machine that helps reduce friction and make it easier to move objects.
