Hsien Loong is still thinking about promotion and career development of his employees. This kind of anomaly only exists in one country and no where else. No where in a democratically elected govt does a head of a political party has the privilege of career planning and development, and a salary scale for politicians as if they were employees of the state. In a normal healthy democracy every term of appointment could be the last term before the next general election.
Would Obama or Cameron be talking about career planning for their ministers with salary increment and promotion to come with it? What is happening here is a unique situation that could no longer exist in the next general election. It is not going to be the same anymore looking at how things are developing. Any political party that is elected to power should count themselves lucky. And to be reelected again, is not going to be a sure thing. In many countries, a two term party is a great achievement that many could only hope for.
What happens if a new govt is elected to power in 2016 and subsequently political offices change hand more regularly? It is something that can happen. To be elected again and again is no longer going to be a guarantee as the political system matures, as the people get wiser and more demanding and more selective.
