The BBC has termed South Africa's evolving stance on polygamy a 'powerful challenge to Western norms.' A more cynical observer might call it a fiscal headache. From my vantage point in the City, this is not merely a cultural squabble.
It is a story about resource allocation, market signals, and the long-term implications for social stability. The government's flirtation with formalising polygamous unions is a reckless gamble with taxpayer money. Consider the paperwork alone.
Multiple spouses mean multiple tax returns, multiple inheritance claims, and a quagmire for the welfare system. The administrative costs will be staggering. And what of the macroeconomics?
Polygamy historically concentrates wealth among a few men, pulling capital out of the wider economy. This is capital flight of a different sort. It creates a drag on productivity as household income is spread thinner.
The 'norm' the BBC celebrates is a recipe for diluted human capital and higher dependency ratios. Markets hate uncertainty. And nothing introduces more uncertainty than a government that cannot decide which social contracts it will honour.
Central bankers take note: social fragmentation leads to volatile spending patterns. The Bank of England already struggles to predict inflation from family expenditure data. Add polygamous households and that model breaks down.
Fiscal responsibility demands clarity. But clarity is in short supply. Instead, we have politicians chasing headlines.
They should be watching the gilt yield curve. That is where the real challenge to Western norms will be felt.
