The financial markets have long priced in the cost of vanity. But a new report from British mental health charities suggests the liability is far greater than previously accounted for. They are demanding a regulatory crackdown on social media, citing a surge in 'cosmeticorexia' among adolescent girls. This is not merely a social issue; it is a fiscal time bomb.
First, let's define the asset. Cosmeticorexia: the pathological obsession with achieving an unattainable aesthetic standard, often driven by filters and curated feeds. The charities claim this leads to mental health crises, eating disorders, and a generation unable to participate productively in the labour market. If they are correct, the future tax base is at risk. Human capital is the most valuable asset on any national balance sheet. Impair it, and you impair growth, productivity, and ultimately, the government's ability to service its debt.
The charities want tighter regulation of algorithmic amplification and age verification. They argue that social media platforms are effectively exporting harm to vulnerable users. From a market perspective, they are describing an externality. Currently, the costs of cosmeticorexia are borne by the NHS, by families, and by lost economic output. They are not priced into the share prices of Meta, Snap, or ByteDance. That is a market failure.
But let's examine the proposed remedy. Regulation is a tax on innovation and efficiency. It creates compliance costs, reduces returns on capital, and encourages capital flight to more lenient jurisdictions. The UK already has a reputation for overreach: the Online Safety Bill was a bureaucratic behemoth. Adding another layer of rules for mental health will only deepen the regulatory moat, dissuading investment in the very technology that could improve lives.
And yet, the evidence is mounting. The charity report cites a 400% increase in cosmetic procedures among under-18s since 2020, and a 50% rise in eating disorder admissions. These are hard data points. The market is ignoring them at its peril. Short-term profits from engagement-based advertising may be masking a long-term liability: a generation of disaffected, unhealthy, and economically inactive citizens.
Consider the parallel with inflation expectations. When central banks ignore rising prices, they eventually lose credibility and must act aggressively. Similarly, if regulators ignore the psychological costs of social media, the eventual corrective intervention could be severe. Better to manage the risk now, with targeted rules, than to face a wave of litigation or a sudden policy swing that crashes the sector.
But there is another angle: the 'bottom line' for users. Social media provides cheap social interaction and entertainment. For many young people, it is a lifeline to community and identity. Restricting it too hard could push them towards darker corners of the internet, where the returns are even lower. The charities must ensure their solution does not create a worse externality.
So what is the prudent course? Perhaps a 'polluter pays' model: a levy on social media companies proportional to the mental health costs they generate. This internalises the externality and funds treatment. Or perhaps we need a 'deleveraging' of online time: encouraging a shift from passive consumption to productive activity. But government diktats rarely foster efficiency.
Ultimately, this report is a wake-up call for investors. The social media sector has enjoyed a long bull run on the back of attention and advertising. But the fundamentals may be deteriorating. If cosmeticorexia erodes the mental capital of the next generation, the internet's largest content providers will find their user base less valuable. The market has not priced this in. When it does, the correction could be brutal.
The charities are right to demand accountability. But the solution must be market-friendly: transparent, efficient, and based on evidence. Overregulation is a tax on the future. Undoing it will cost far more than preventing it. For now, I am watching the gilt yields and the social media stocks. The risk is not yet priced. It will be.
