To fund their expenditure
[Plz. read as foreign visits, helicopter+plane rent,security,cars,bills to name a few] the authorities are just blatantly taxing the common people. Each and every possible point to tax is being probed for filling the coffers. I pay taxes to see the ministers flying high in paid helicopters, travelling in lavish cars, living in luxurious bungalows, renting lavish suites in hotels, roaming around with 10-20 commandos to just name a few privileges.
CTT is another ruthless decision going against trader community at large.
