Absolute power leads to absolute corruption. Democracy is far from perfect and the presidential system has its various flaws - even the US has certain problems at times. South Korea needs to revamp its constitution to introduce a modified semi-presidential system, and the presidency should be publicly declared to be above party politics. At the same time, the heads of the judicial and procuratorial branches should be directly elected in alternating years and 1/4 of all MPs should face election each year.
