sg has been self sufficient 10 years ago, sg only imports water because it is cheaper. sg can produce water to cover 2x-3x of what it uses.

sg can send all malaysians back home and replace them with 1 billion indians or chinese or thais EASILY, just cancel all their work visas and within a year all gone. many chinese/indians/filipinoes, all want to work in SG. there is no lack of low skilled workers wanting to work in SG

buying food from thailand is not much more expensive than buying from msia, thai rice and msian rice same price anyway.

u use the tap water in johor, it is so fresh and clean, all colourless can drink straight. because sg treats the water for johor.
u go kl and use the tap water, it is yellow with sediments, a bit disgusting.
u see the difference in STANDARDS when singaporeans do things and other ppl do things?

without singaporeans investing and shopping in johor, tomorrow all can go back farming vegetables, all the malls and shops and service sector will close.

sg has no need for msia for anythiing, from food to workers.
everything can be swtiched to another source.
the only need was water but that has ceased 10-20 years ago. even before that, 30-40 years ago, with some water rationing, sg will be okay even if water was cut.

sg will hit gdppc 80k in 2030, while msia will still be stuck at 15k (the kind of standards sg had in 1980), and politicians with brains stuck in 1970s will still talk about sg being 'little brother' lol.

sg just got 4 new submarines and will be getting f35 soon. the japanese are getting 100 f35s as well.
good luck
