I hadn’t considered that. It sounds like another reason why insurance is broken. If you have two options, $100 premiums and $100 cost; versus $1000 premiums and $1000 cost; the net gain on premiums vs cost is the same, but the investment income over the interim will be higher when the total amount of money in the system is higher.
I would be interested to see the average premium price compared to total investment funds across different geographies and times
