Corruption affects common people on a daily basis. It affects the poor in the worse possible ways and closes the opportunities that legally may be there but practically are not available unless a bribe is paid, a favour done or there is some nepotistic connection exists. It disallows inclusive growth. It affect's an ordinary citizen's abilities to maintain basic living standards, access public services like health and education and social benefits among several other things. It leads to misuse of the available public resources, and therefore, economic growth does not reach all sections of a society.
Communalism destroy the fabric of a society and destroys social cohesion and harmony and take destoys peace and stability which are pre-conditions for development. Communalism increases poverty by preventing movement of labour, capital and other public resources by restricting these within a particular community. It takes social trust away and creates a sense of instability for those who are not part of that community. It affects people's ability to generate more resouces using the current resources because it creates and environment in which property and other liquid resources can be acquired, owned or transacted for benefit only by a certain community based on their claim of a traditional precedence.
