S$2000?? Not a realistic figure. WHy you only show us possible expenses ? You should also calculate the income gain by people who work in singapore and stay in JB...eg. $4000 x 2.5 = RM10000 / month. So even if you pay S$1000 monthly, you still have balance RM7500 to spend in JB (excluding CPF contribution).
What a dumb way of reasoning!
Who are those who drives an SG plate vehicle daily into Singapore to work?
Who are those who are driving a MY plate vehicle into Singapore to work?
They are mostly Malaysian or SPR, who don't mind spending 4 hours daily (both ways), coming out early and going home late, commuting to work in SG in order to earn SGD.
And they are mostly NOT very high wage earners.
My SPR account manager is only paid about $S3,600 and she drives to work in a MY plate car.
My Malaysian IT technician is only paid about S$3,200 and he drives to work in a SG plate car.
These people and thousands of others like them will be the ones that will be badly affected with the new rules!
However, on the bright side, there will definitely have less traffic jams at the CIQs
