How do SA bring a lot of money to the table?They won't be keen to, until/unless the money looks too good to refuse, then they'll be falling over themselves to welcome them. The Welsh, Scottish and French are all in varying degrees of financial trouble and the English aren't exactly without issues either. If they see South Africa as a solution, they'll take it.
That said I don't think it particularly likely at the moment, but it's not that improbable either.
