Having taught in schools for years? Treat companies that make addictive products the same way we treat drugs, alcohol and tobacco. Kids want them, particularly teenagers. We aren't perfect at stopping their access. But we can make a best attempt.

It would be hard, and it would be 'anti-capitalism', but, I think we have done real long term damage to a generation, and I think in 20 years, like Tobacco, it I'll turn out the companies knew how much they were damaging children and covered it up.
