Earlier quoted context omitted.
That's not really how it works. The "ever increasing" pie would have to come directly from increasing subscriber premiums, not from cutting costs and pocketing the difference the OP indicated. It doesn't matter how much they play with pricing on the back end, the company can't make more than 20% profit from subscriber premiums.
There is a whole lot of backscratching with the profiteers taking their cut of the 80%. That is why we get $30 Tylenol pills under the guise of "care".
That's completely illegal and it's just too noticeable for them to do it large scale.
The OP was making a baseless claim because they didn't know what they were talking about, and you're now grasping at straws supporting their claim for some reason.
