BYAIRMAIL, you have lost all credibility since you started to just make up things.
1) Robert Mugabe was not a "guest of honor" at the opening ceremony. The head of state of all FIFA members are invited to attend. So I don't see how you think people did their utmost to make him welcome. Many heads of state did attend, and will continue to attend the tournament.
2) When did Japan openly admit to making a mistake hosting the World Cup? If it were such a mistake why are they bidding to host it again? They are bidding to host both the 2018 and 2022 event, as are South Korea who they jointly hosted it with in 2002.
The big difference between the Japanese/Korean World Cup and our own is that we are using far fewer venues, 20 versus 10. Of those 10, only 5 (call it 6 with Soccer City) are new builds and most will do just fine after the World Cup. The only stadium's with serious concerns going forward are Nelspruit, Polokwane and Port Elizabeth. Cape Town was a concern but will do okay. The 2010 World Cup is already immendly profitable, and has cost less (in real terms) than any recent World Cups.
You don't like the World Cup - we all get that. But there is no need to just continuously trash it - it serves no purpose but to make YOU feel better about it all. The large majority of South Africans are loving this World Cup and they think its money well spent.
Your statistic about 5% of people paying 90% of tax is blatantly false, but that said, remember that 10% of South Africans earn more than 60% of all income!
