Even the age rating factor is capped at 3, so there are also massive wealth transfers from young to old.
Mathematically, health insurance premiums in the US are more tax than insurance premium.
The ACA doesn't prevent some magical fairy-dust AI from pricing premiums, though, which is currently all the rage amongst insurers. (Not because AI will be accurate or anything, but because it offers a completely opaque pricing process.)
