After that only the fall follows, due to economic decline. This is exactly what happened here. The main cause of the hypocrisy is simply the universal vote. It is a paradox to ask stupid people to choose clever representatives. In order to obtain their votes, the sly politicians make unrealistic promises.
Politicians everywhere do it.
Of course we do not want to renounce the universal vote as long as we do not have a better solution. People from some countries know to use it reasonably while those from other ones are easily deceived. It is a matter of how to use it. Our system was the most hypocrite that humanity has ever invented. I know some people will say that there is corruption, hypocrisy, et cetera in occidental countries too.
