Its amazing how people are still unaware of this after so many documentaries, reports, advocacy on the matter.
Just google. "Neoliberal privatization tactics", "Economic hitmen" (that was a pretty popular take), neoliberalism etc.
> more (old) people are using health care.
Irrelevant. The number of older people in any country is not enough to bankrupt healthcare systems Healthcare is a function of the percentage of national GDP spent on it. If there are more people, you have more GDP, you can spend more. If you have less people, you cant spend more but you also have less people.
Blaming the problems on irrelevant 'reasons' is one of the ways in which privatization is hidden from sight - just check how many cuts have been made to the healthcare spending in your own country in the past 40 years, and how much. There you will have your answer.
