Haha this is what I wrote to [email protected] on their request for feedback to make better use of Singapore's land......hehe
Suggestion: Reduce the no. of golf courses and make more use of JB's golf courses. Improve transport links with JB via 3rd or 4th link, and build more MRTs to link to JB. This ensures a sizeable no of malaysians can live in JB and work in SG (ie New Jersey and New York), and improve Singapore's liveability. Labour intensive industries can be shifted across the causeway to optimise land usage, but again, this needs to be supported by good transport linkages.
Not sure if goverment will accept about this while you can free up some land in SG for other use, but at the same time you are also shipping out $$ to JB.
