Explanation: Democracy in itself is a system in which people directly or indirectly decide important issues and political decisions. Like any other system, democracy also carries with it the germ of corruption that corrupts the system from within, which in perspective, as something does not change, leads to a certain form of tyranny. When corruption starts destroying the system, then the system is no longer guided by the interests of citizens, but by the interests of individuals or interest groups. To prevent this, there are political parties that represent the opinions, attitudes and lifestyles of different social classes, groups, and even types of people. These political parties confront the views, or so it should be, of those they represent and influence political decisions on all sides, shape and balance the system as much as possible. By combining party attitudes and policies, democracy, to the greatest extent possible, is never fully possible, is designed to meet the needs of the majority as much as possible.
