"freedom from", you will not be given a prevention from some horrible disease. You can buy it if you can afford it, but a significant portion of the population can't, and some of them will not be able to enjoy life because of it.
"freedom to", a prevention will be provided. You can always decide to take alternatives, if you can afford it. A significant portion of the population can't. They will be able to enjoy life.
Equating freedom with the liberties the rich have is absurd. In any society, the rich will have the most freedom, even in the most oppressive ones. The true litmus test for freedom is seeing the freedoms the poor can enjoy. By that standard, the US doesn't score very well.
