What important power did the national government lack under the articles of confederation?

Answer.

An army, power to tax the states and the states had more power than the federal government.

Explanation:

The reason the articles failed was because the feds were too weak and the power was unbalanced.

an informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
