While bribery is one of the big problems, it is often based on the fact that a politician has been around (and groomed) for a long time. That’s one reason why a professional politician is a danger to society. The other point is that most politicians have never experienced real life.

Look at the US: guys from rich homes, having studied law and politics at prestige universities where they started building up on political contacts, and have been nothing but politician since then. Some have had political offices for 40, 50 years. And not a single hour of real life experience.
