"Equal Opportunity to All" says Democracy But is it followed by any Politician or Political Party?

What is happening in politics all over the world is that every politician wants to retain his/her power as a Member of Parliament or Assembly. Is it fair on their part? Absolutely not. The Constitution says that equal Opportunity should be given to all citizens. Though it is not possible to accommodate all at least the system should ensure that no one should be given a second chance to hold the SUPER SENSITIVE post as a member of Parliament or Assembly for the reason that they handle a huge amount of Public Money. We all know all Government Servants who are posted in a sensitive post will not be allowed to continue for more than 3 years for the same reason stated above. If the situation is such how can we allow the politicians to continue for another term? It is apparent sometimes if any Constituency is allotted to a female member, at once they obtain ticket for their wife or children to contest irrespective of the Political parties. Every one of us knows that the said Politicians have made substantial wealth by using and misusing the power vested on them. It is an open exploitation of the citizens by the Politicians. It will not be a Democratic rule but a King or Queen's rule only. This is to be regulated by the High Constitutional body ie the Election Commission. Let us all pledged to put an end to this mischievous practice of all Political Parties and the Politicians in a Democratic Country all over the World.
