I don't know what country you are in but definitely not describing South Africa.
Of course I'm not. South Africa has an interventionist government.
If Vodacom sells you something and you have a problem with them and cannot fix it you can't just cancel your contract and go somewhere else, you have to pay the full contract amount in advance to cancel. And if you cancel, where do you go? MTN with their serious biling issues? Cell C with their below par reception? (these might be historical references that have improved or been fixed and is just used as illustration).
Have you ever wondered why there are so few cellular providers in SA? Do you think it's from want of competition? No, it's because you have to get a "license" from the State to operate one. The major cell phone companies like Vodacom and MTN even have the State owning shares in them so of course they are going to behave as a cartel, they have the State as their best friend and partner! Once again, you only have State interventionism to blame for these problems.
There are 3 mayor supermarket chains. Where else will you buy? Massmart owns (and owned) many different companies and some even "competed" against each other (old Dions and Game). Same with Famous Brand and fast food.
This is a horrible example, there is so much competition for grocery and food provision it's a wonderful thing for consumers: Checkers, Pik 'n Pay, Woolworths, Spar, gas station quick shops, stand-alone "cafes" and convenience stores, not to mention all the delis and restaurants. Of course this does not mean major players won’t attempt to get subsidies from the government or rent-seek for favours, but this is a problem with the State, not the market.
Telkom is a landline monopoly, if you get poor service, where will you go.
Just like the cellular provider example, why was Telkom (until recently) the sole provider? Oh, that's right, it used to be an actual State enterprise, but then became "private" with the State as a major shareholder whilst, simultaneously, the State controlled all the licensing and regulation! Interventionism is bad. Hello?
Competition is limited in the South African market and thus the consumer is robbed of his power. The CPA creates artificial competition.
The notion that the State needs to create artificial competition is absurd. In an open market competition will appear wherever an opportunity exists. As I have said before, the CPA is just more State interventionism, the fact that it is supposedly on the side of the consumer does not automatically make it beneficial.
BTW, thanks for conceding, Kage. Better luck next time.
