The whole approach to the ills of modern life is so stupid.
Preach individual responsibility all you like but the fact is that almost everything we do / rely on to live has a cumulatively negative effect on our health both physical and mental, the environment etc etc.
Because of greed and capitalism and the reliance on consumers to keep buying all the stuff we are simultaneously told we shouldn't because it's bad in every way, we live in a time of complete cognitive dissonance.
The answer is always to bilk more money out of the consumer rather than address the sources and reasons for their "poor choices" and frame it as concern fir health and well- being.
Consumers buy what is offered to them, and the competitive market spends billions on figuring out how to get them / us addicted to products, services and leisure pursuits in order to maximise profits.
Capitalusm runs on creating innovative solutions to problems - and then when a market is saturated actually inventing problems to convince us we need the newly minted solutions.
Will a sugar tax really improve children's dental health, or is it a cynical ploy to extract extra profit for the government and the corporations who work in lockstep behind the scenes to make sure every penny that can be is extracted from the consumer?
This approach is akin to offering a child an ice cream and then slapping them upside the head on the tenth time and telling them off for enjoying it. It's abusive on an insidious level.
"Here is a complex challenging world full of lovely things and technology and things which are difficult to exist without - now we are going to simultaneously blame you for being a good consumer and make you pay, pay, pay."
It's in every facet of our lives because money. It always boils down to money.
A proper dental programme would be a better answer that could encourage education but it wouldn't be as profitable as a sugar tax. They don't care about our health, safety or welk- being - they care about profit.
