Extravagant expenditure in feast festival obstructs the development of society

Extravagant expenditure loses the essence of the festival and sometimes becomes a show for attention-seeking people.

Explanation:

Often it takes some expenses to make a festival cheerful and this allows us to devote more time with our friends and family. However, the other fact is that one doesn't need money to spend time with loved ones. The lightness of festivals sometimes blinds us that we cannot see the real motive of the festival and look for material pleasures in it. Society is affected because the potential capital which could be used for its upliftment is wasted on a extravagant leisures.

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.
