What a horrible product to offer. Couples planning to marry will almost certainly be more optimistic about their chances for eventual divorce than the facts warrant. And even if they're realistic, there's immense social pressure not to admit it. This company's business model is basically going to pressure people into signing up even if it's a bad decision. And then to cap it off, they'll be collecting on the debt right when couples are going through a terrible time.
I feel like this is the sort of business that Martin Shkreli would start if he were outright evil instead of just a sociopath.
