Logical for the broker, no doubt
I've heard the commissions paid are just insane.
Commissions for VA are 3% of the deposit, same as any front loaded mutual fund. Not insane at all. While you may personally prefer no load funds, front load funds make sense to other people.
Commissions on life insurance could be up to the full first year premium, but thats between the insurance company and the broker. The insurance product still has to perform for the client and it does, as long as you have anything but a short horizon for investing.
Again, I wouldnt recommend either of these as investments unless the client already is fully funding other tax advantaged vehicles first.
