I quite agree with a sugar tax, then the profits used for whatever. The massive amounts of diabetic clinics we shall need in the future.
I also think the age on cigarettes should be increase by one every two years, so we eventually remove smoking. While at the same time slowly losing the tax we generate from it.
Long term policy however is something which governments do not seem to care about.
We need a 25/30 year health plan, not biased by politicians. They set a future funding budget, and the system generated is defined by such an amount, anything above or outside of it is funded privately, or by charities or insurances. I doubt we could generate such a study currently. A full look at everything, and then the politicians from whoever is in government at the time have to implement it. Then at least the people of society know what their healthcare is going to provide from 2020-2050, and what it will not provide.
This should involve and include public health drives, as they should be integral to such a system. No Sir you are 30 stone, and have done nothing to hep yourself, we won't be consider hip ops or the meds you need until you bother you ass to start the correction.
You can't do it now, but you can in 2025 when he's had 10 years of warning towards such a goal.
If he doesn't like it, he can apply to Blobsters.com the charity for fatties who need stuff because they decided to be superfat ad do nothing against about it. I am picking on fat as it is an easy example, but the same holds true for diabetics who do nothing to control sugar intake, and COPD who continue to smoke 80 a day.
