Tongues

Tongues relates more to the mindset of people rather than the langugae. Language never caused people to be separate from each other or to not work together. What has, is essentially any situation that causes people to fight amongst each other and this in turn is brought about by different mindsets, beliefes, convictions. The negative and counter productive forces of these elements is what causes people to fight amongst each other and while people are busy fighting amonst each other, they commit all their time energy and money (resources in short) to it, causing them to not have time for anything else, especially not build something that requires the co-operation of many.
