re: Give me scenarios where whole life/VUL would be a good idea to own

Self employed, maxed out on deferred investments, and make too much for Roth. If you don't fit this, there are better investment vehicles alongside a term policy.

There are ways to roll in short term, long term disability with the Life insurance policy. These are things that can be available to people employed by others that a small business owner doesn't have access to.

In my case, I have one.
I took a while with accountant helping to decide
I took the cost of 20 year term life, short term disability, long term disability, and the cost of a couple of other small riders that I wanted. The overall cost wasnt that far off.

It's not huge but if I make it another 16 years, the growth will be mine tax free. The taxes will be pretty high on my deferred because I don't plan on retiring. I'll still own the business while taking retirement distributions distributions.

I think as a primary retirement vehicle it's not the best. If you fit certain parameters, and you expect your post retirement age taxation to be as high, or higher than it is now, it can be an adjunct to a balanced portfolio.
