Is the two party system good or bad for America?

The framers of the constitution had a goal of strengthening the government yet limiting the government's potential strength at the same time. However, I do not think that they anticipated that there would be a tradition of two parties dominating the government they carefully designed.
The Democrat and the Republican parties have grown and currently dominate the political world. Two parties, two choices, that is it. We are supposed to be a representational democracy but how representational can it be if there are only two parties? The people of America have more than two ways of thinking, more than two ways of believing. With a nation the size of ours, there are bound to be differences in beliefs from one person to another and the only way to represent everyone as accurately as possible, there needs to be more than just a two party system. There should be a multi party system, like that of most of the European Democracies.
However, many people are opposed to this saying that it will make things more complicated and it will cause more disunity. As for the first part, it has become somewhat of a tradition to chose convenience over what is better as a whole. As for the second part, we are already severely devised between the two parties as it is.
Both parties have grown so strong and keep loosing power between each other that they keep trying harder to obtain power and keep power. This makes it so that they are divided to an extent that they do everything in their power to stop the other party. If there were multiple parties, they all would be limited in their power. No party would be large enough to succeed on their own so they will be forced to work together to achieve their goals.
Along with the parties being forced to cooperate, they would also be just small enough so that one wrong move and the public would have enough to do something as opposes to the public trying to fight one of the massive parties that exist today.
