There was a good discussion in The Economist four months ago but which I saw only today. It discusses the irony of poor economies in Africa and elsewhere which have some facilities against infectious diseases, but very lacking in treating NCDs and the latter are now the main killer diseases in the continent
Chronic diseases in developing countries
Poor countries are developing the diseases of the rich, with lethal consequences
I would like to believe that if people have the resources to spend on heavy eating, or heavy drinking and/or smoking, and since they know, fully or partially, that excessive intake of those things will lead to some undesirable health outcome someday, then they should have resources also for future treatment, fully or partially. Now, since the prevailing belief is that "health is a right" and access to healthcare is a government responsibility, such provisions are often enshrined in various national laws if not in the country constitution itself, plus various international and multilateral health agreements, there is a tendency for many people afflicted with such diseases to feign poverty and expect or demand bigger government subsidies for their personal maladies.
Of course these people know that no one put a gun on their heads so that they should have higher than normal consumption of food, soda, alcohol, tobacco and other stuff into their body. They know that it was mainly personal choice for their lifestyle, including having a more sedentary living.
The best treatment against NCDs is preventive, not curative. These include, among others: One, restraint from regular high consumption of food, alcohol and related stuffs,coupled with a sedentary lifestyle. And two, getting vaccinations if such medicines are already available at a more affordable price.
A related measure, is for people to get or buy private health insurance, to supplement whatever health insurance that the government, national and local, will provide.
It is important to remind people that healthcare is first and foremost, a personal and parental or guardian responsibility, not government's. Government assistance and subsidy should better be limited to preparing for, or treating non-infectious diseases..
