Is this a scheme to prevent the members of a two party system from coalescing into a single party?
I personally believe the best form of democracy would be something along the lines of a liquid democracy, coupled with a constitution that protected the rights of everyone (to ensure those with minority viewpoints would always be entitled to a base level of respect). If you're interested in finding out about liquid democracy, this video provides a good introduction:
That concentration of power was so traumatic to the political system that, for the next 20 years, a long sequence of steps were taken to prevent it from happening again. Presidential terms were limited to a maximum of two, and the constitution was eventually rewritten in a direction that removed the presidential powers that Kekkonen used (and abused) to override parliament.
