The government fixes the price of petrol, ( gas in American language), but Sasol gets fined a few billion for fixing the price of some minor wax bi-product.
The government fixes the price of VAT, ( value added tax ) at 14% on all goods including foodstuffs, but Tiger Brands gets fined a few billion for fixing the price of bread.
The government, ( and councils ) fix the rates of interest, income tax rates, property rates, electricity rates, motor car licence rates, etc. etc.
Who is going to fine them for price fixing ?
Who collects the lolly ?
What do they do with the lolly ?
Probably pay themselves big fat bonuses for having caught out some dastardly price-fixers.
