Corruption! Who's responsible??

Many of us blame politicians for corruption. But actually, politicians only do what people want them do. When a well known corrupt politician is brought into power, it is the

people of that constituency who are corrupt. The people of that constituency encourage the politician to develop only their constituency well while ignoring other areas. When people become purchased voters, they actually encourage the politicians to do bigger scams in future. When people accept vote bank and appeasement politics, they encourage the politicians to not do any constructive developmental work during their tenure. When people bribe the traffic police, they ask the police to stay corrupt. So then, who is actually corrupt?? And why blame the politicians??
