I doubt they will do it voluntarily. Surely this will have serious cost implications for the country. Martin van Staden, a legal researcher at the Free Market Foundation, says: "With the 2010 cost estimation inflated with the Consumer Price Index in 2017 terms, the NHI will cost the taxpayer R368,8 billion by 2025. Even this, however, is a conservative estimate in light of overly generous future growth estimates provided by the government. Furthermore, in 2017 terms, the NHI will cost South Africa R156 billion every year from 2025 onwards – assuming we achieve two percent growth – which is roughly equal to four 2010 Soccer World Cup tournaments, or 1,4 million government houses a year. The NHI would double South Africa's health budget." Who will pay for it? The essence of the NHI is that the "rich will subsidise the poor, the young will subsidise the old, and the healthy must subsidise the sick". Motsoaledi notes: "At present, the poor subsidise the rich." Will everyone agree with this view?
