Because the horse makes in addition some "Work". This is Force x Distance

When a horse pulls on a rope that's attached to a cart, The rope has a tension force that "pulls" against the horse. But at the same time the tension in the rope "pulls" on the cart, which then "pulls" on the rope. The net force on the cart, if friction is not too great, causes the wagon to move, and the rope moves with it.
It is always the net force on each individual object that must be considered when deciding whether something will move. As long as the net force on something is not zero, it will move.

All the six answers suggested to you are WRONG. For the forces to get cancelled they have to be acting on a single point. In your example (or any other event) the force of horse is acting on the cart and the reaction of the cart is acting on the horse. This is the reason why the both cart and horse experience the force (put yourself in both the places and think)

When the horse is pulling the cart, they're acting as a single mass unit, what's happening is the horsecart is exerting force against the earth, and since the earth has more mass than the horse/cart, the earth moves very minimally while the horse/cart moves alot.

Yes they're applying equal force to each other, however the horse is also applying more force on the ground than the cart is which makes it (the horse) the controlling factor in the motion of the pair.

The horse is pushing the cart, because of the harness attached to the horse. The horse is pushing against the harness to pull the cart.The harness is pulling the cart, the horse is pushing the harness.
There you go.

The horse "creates" a internal force in the system. The action-reaction applies when forces come from the outside of the system

If I understand your question correctly...the cart does resist movement (an object at rest tends to stay at rest), but being on wheels it does not generate as much friction as a non-vehicle would.
