The realities of a politician job are wildly disconnected from a "real world" job, though. No "fire/hire at will", for example - once a politician is elected, he/she can serve the term without having to fear unemployment on the next day. No matter how he/she performs, the only way to get rid of an elected politician is criminal behaviour (and as seen with Arpaio, sometimes even openly defying judges is not a reason to be forced to quit).
In Germany, all members of parliament also get a pretty pension package - minimum of 1.682€ per month, which is FAR more than many old people ever get.
Politicians NEVER have to experience the worries of "normal people" like "how am I going to survive as a pensioner?", "how do I feed my kids when I don't have any money left?" or "how am I going to pay rent this month?" - and with a greater and greater rate of "working poor" or unemployed people, the disconnect will rise accordingly.
