Right now the only difference between SG and Johor is merely safety and physical infrastructure development

If they can raise salaries to match the cost of living, crimes will go down as a result

Trust me, its only matter within 10 years before they catch up with SG in this aspect.

In terms of indirect taxes, Singapore is still the highest and that makes SG unfavourable.

Thus there is higher risk of spending shift to Malaysia and tax revenue loss

It is probable that Johor will be the main focal point of development rather than SG, Johor will benefit more.

IMO the SG Johor SEZ should not proceed
