Singapore should plan for a population of 10 Mil, says Mr Liu Thai Ker.
Mr Liu was CEO of HDB from 1979 to 1989, and then CEO of URA from 1989 to 1992. See this - http://eresources.nlb.gov.sg/infopedia/articles/SIP_584_2005-01-22.html
I think Mr Liu knows full well that our tiny island can take a population of 10Mil. We just need to carve out more space, and perhaps devote less space to certain industries that require a lot of land.
Anyway, before you think that 10Mil is way too many people for Singapore, do consider the fact that for our little island to be relevant to the rest of the world, we need a sizable population. This world is all about cities.
Many large cities (5Mil and above) are sprouting all over the place, especially in China and India. The urbanization trend is not stoppable.
Anyway, planning for 10Mil doesn't mean that we will necessarily get to 10Mil. However, I think with the recent squeeze and jams, it would be much better to build the infrastructure in advance, rather than try to catch up later on.
Why do we need to many people? Well, I leave that discussion for another day.
Happy investing!
