This picture puts it best, the effects of the new GST (Goods and Services Tax), when compared with the old GST (Government Service Tax).
When we were being educated on GST, the rate used in examples was 4%. Even before introduction, it has been increased to 7% (to test the reaction of the people?), a whopping 75% increase in rate. Even when it was mentioned at 4%, many people like myself, had warned about the possible change in rate at will by the government, once it has been introduced. Well, BN can now claim they have the mandate to introduce GST, long delayed because of their worry over its effects on GE13, and increase the rate if and when necessary (to reduce high deficits).
