If you willing to pay this charge, then the benefits are following:
1) the cash value in your account is tax free for all future capital gains, so if you can build a sizable portfolio, you can off set the high charge.
2) the cash value in the account is lawsuit safe, meaning if somebody sue you, they can not touch it.
I get into it because above reasons, now I found I am trapped.
I think only <1% people can benefit from this type of account, hope you are those 1%.
