On politicians and talent

Well another drama unfolding on the Iraqi oil scam.And as is usual morality is defined by which side of the political spectrum you are on. It really is a disgrace that otherwise erudite people, corrupted by power, twist an indictment which say they made a profit from an illegal activity as protests of innocent because the charge was not making illegal money but misusing position!
Incidently, our esteemed Prime Minister had given the gentleman a clean chit the moment press started on commenting this. Later when the real powers that be, got accussed the same guy our PM insisted was cleaner than a hound's tooth, was investigated and found guilty. Apparently prime ministers of India do not give clean chits based on truth and honesty. I used to really respect M M S now I just find him another two faced politician who will cling to power, morality be damned.
I have come to the conclusion that corruption will never go from politics. The real issue here is maybe that the people we choose are wrong. These are people who rose to top possibly not because of political competence but rather because of servility to a family. In my view, a politician who is actually good in politics as opposed to a boot licker or criminal, has a greater chance of being a good administrator because a politician by definition is a leader, and leader need only pick and motivate the right followers.
Look at Laloo. While he was doing the politics of poverty, he was a blot on nation. Booted out for same, he flipped like a good politician and now railways are toast of the nation. Yes, I do consider him a great politician even though I detest his brand of politics. The point here is that he rose because of his competence and once channeled in the right direction, the results are good.
Problem is that most of our current leaders rise either because of criminal links of family connections, and that is why we see so few respectable talents. What I do wonder is why we elect them (and yes I do vote in elections).
Maybe, we get what we deserve. Maybe we have such venal politicians because inherently we have lost our respect for good things in life.
